This book was released on 2009 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility is explored by single-beam coherent anti-Stokes Raman scattering CARS spectroscopy of gas-phase diatomic molecules related to combusting flows, with implications for gas-phase thermometry. We demonstrate CARS of gas-phase N2 using a shaped 7 fs laser pulse, investigate the dependence of the CARS signal on the total pressure of the probed environment, both in pure N2 and in mixtures with Ar, discuss the observed signal-to-noise ratio, and suggest improvements to be considered for reliable single-shot measurements at flame temperatures.

Download or read book Single Pulse Phase-control Interferometric Coherent Anti-StokesRaman Scattering Spectroscopy (CARS). written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In coherent anti-Stokes Raman scattering spectroscopy (CARS) experiments, usually the amplitude of the signal is measured and the phase information is lost. With a polarization- and phase-controlled pulse shaping technique, the relative phase between the resonant and non-resonant CARS signals is controlled, and spectral interferometry is performed without an interferometer. Both the real and imaginary parts of the background-free resonant CARS spectrum are measured via spectral interferometry between the resonant and non-resonant signals from the same sample. The resonant signal is amplified significantly by homodyne mixing with the non-resonant signal as a local oscillator, greatly improving the detection limit.

Download or read book Tomographic State Reconstruction and Time Resolved Surface Enhanced Coherent Anti-stokes Raman Scattering in the Single Molecule Limit written by Steven Yampolsky and published by . This book was released on 2014 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time-resolved, surface-enhanced, coherent anti-Stokes Raman spectroscopy (tr-SECARS) is ideally suited for preparing and probing vibrational coherences in molecules. By enhancing the local response of a single molecule with a dipolar nano-antenna, vibrational dynamics have been measured at the single molecule limit. In contrast with tr-CARS measurements in ensembles, the vibrational coherence of a single molecule is not subject to pure dephasing. It exhibits characteristic phase and amplitude noise, which allows the statistical distinction between single, few, and many molecule sources to be determined. To build on the current work, by using three unique pulses to spectrally fiter the response of the molecule, the characteristic noise can be isolated and measured background-free. If the probing of a superposition state is carried out over a real resonance, then it is possible to tomographically reconstruct the complete description of quantum dynamics in phase space representation via the Wigner Distribution Function(WDF). The WDF can be reconstructed from either the wavepacket via Wigner Transform, or an experimentally measured density, via an Inverse Radon Transform. The calculations presented here highlight the necessary conditions in order to reconstruct the WDF with delity from a proposed experiment and compare the density derived WDF with that of the wavepacket. The principle is firstly demonstrated using a Kerr gated detection of emission from an evolving state on a bound harmonic potential energy surface. The model is then explained in the case of a proposed spectrally resolved transient grating experiment (SRTG). The WDFs generated from the limiting conditions show that the reproduction delity of the experimentally derived WDF are dependent on the probe, utilized to measure the evolving superposition, and the curvature, or the vibra tional frequency of the potential energy surfaces, and the dephasing time of the vibrational superposition states. Given two potentials, I show that it is possible to optimize probe pulse parameters to improve the delity of the state reconstruction. Due to the variational principle, the negative volume of the WDF, or the Wigner hole, can only be reduced via measurements - the pulse parameters can be optimized iteratively even when the molecular potentials are not known.
Download or read book Single-pulse Coherent Raman Spectroscopy in Shock-compressed Benzene written by and published by . This book was released on 1983 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Single-pulse backwards stimulated Raman and reflected broadband coherent anti-Stokes Raman spectroscopy (BSRC and RBBCARS) have been used to measure the vibrational frequency shifts of the 992 cm−1 ring-stretching mode of liquid benzene shock-compressed to pressures up to 1.2 GPa. The resulting shifts of approx. 7.5 cm−1/GPa in the dynamic experiments are compared to spontaneous Raman-scattering measurements of heated samples compressed in a diamond-anvil cell. RBBCARS was used to simultaneously measure the ring-stretching mode vibrational frequencies of liquid benzene/liquid perdeuterobenzene mixtures shock-compressed to pressures up to 1.53 GPa. Additional experiments that demonstrate the difficulty of using polarization-sensitive coherent Raman techniques, such as Raman-induced Kerr effect spectroscopy (RIKES), in shock-compressed samples are described.

Available in PDF, EPUB and Kindle. Book excerpt: The laser as a source of coherent optical radiation has made it possible to investigate nonlinear interaction of optical radiation with atoms and mole cules. Its availability has given rise to new research fields, such as non linear optics, laser spectroscopy, laser photochemistry, that lie at the boundary between quantum electronics and physical optics, optical spectros copy and photochemistry, respectively. The use of coherent optical radiation in each of these fields has led to the discovery of qualitatively ne\~ effects and possibilities; in particular, some rather subtle effects of interaction between highly monochromatic light and atoms and molecules, in optical spec troscopy, have formed the bases for certain methods of so-called nonlinear, laser Doppler-free spectroscopy. These methods have made it possible to in 5 6 crease the resolution of spectroscopic studies from between 10 and 10 , lim 11 ited by Doppl er 1 i ne broadeni ng up, to about 10 ; at present some 1 abor atories are developing new techniques that have even higher resolution. The discovery and elaboration of the methods of nonlinear laser spectroscopy have resulted largely from contributions by scientists from many countries, in particular from the USA (Massachusetts Institute of Technology, Stanford Uni versity, National Bureau of Standards in Boulder, Harvard University, etc. ), the USSR (P. N. Levedev Institute of Physics, Institute of Semiconductor Phys ics in Novosibirsk, Institute of Spectroscopy, etc.

Furthermore, Raman and IR spectroscopic imaging have become key technologies for the life sciences and today contribute tremendously to a better and more detailed understanding of numerous biological and medical research topics. The topical structure of this new edition is now subdivided into four parts. The first treats the fundamentals of the instrumentation for infrared and Raman imaging and mapping and an overview on the chemometric tools for image analysis. The second part describes a wide varie-ty of applications ranging from biomedical via food, agriculture and plants to polymers and pharmaceuticals. This is followed by a description of imaging techniques operating beyond the diffraction limit, while the final part covers special methodical developments and their utility in specific fields. With its many valuable practical tips, this is a must-have overview for researchers in academic and industrial laboratories wishing to obtain reliable results with this method.

Download or read book Coherent Anti-Stokes Raman Spectroscopy of Shock-compressed Liquid Oxygen written by and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Vibrational spectra of liquid oxygen, shock compressed to several high-pressure/high-temperature states, were obtained using single- pulse multiplex coherent anti-Stokes Raman scattering (CARS). The experimental spectra were compared to synthetic spectra calculated using a semiclassical model for the CARS intensities and best fit vibrational frequencies, peak Raman susceptibilities, and Raman linewidths. Up to the maximum shock pressure of 9.6 GPa, the vibrational frequencies were found to increase monotonically with pressure. An empirical fit, which could be used as a pressure/temperature/frequency calibration standard, showed that the Raman frequency shifts could be accurately described by linear pressure and temperature dependences. Above /approx/9 GPa, the liquid oxygen opacity at 632.8 nm increased rapidly, presumably because of proximity (collision)-induced absorption. Calculations showed that the induced absorption did not resonantly enhance the CARS spectra, but did attenuate the laser beams and the CARS signals. 33 refs., 2 figs., 1 tab.
