Book Synopsis Raman Spectroscopy of Gases and Liquids by : A. Weber
Download or read book Raman Spectroscopy of Gases and Liquids written by A. Weber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Raman effect is a most useful tool for the study of molecular vibrations and molecular structure. Information about the structure and symmetry of molecules, as well as about their vibrational energies can be obtained to a reasonable degree of satisfaction from their infrared and Raman vibrational spectra. The body of knowl edqe of the vibrational infrared and Raman spectra of molecules is immense and is now so well organized and understood that it is found to be represented in any stan dard upper level undergraduate curriculum in chemistry. The rotational energies of a molecule and quantitative details about its structure can only be obtained through the techniques of microwave, and high-resolution infrared and Raman spectroscopy of low pressure gases and vapors. The results of such investigations are of interest . not only to the academic scientists, but also to scientists and engineers who are active in applied fields of chemistry and physics, as well as the atmospheric sciences. This book deals with basic investigations of the Raman scattering of light by gases, with some attention also being given to liquid substances. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is described in Chapters 2 and 3. The all-important intensity parameter, the Raman scattering cross section, is treated in Chapter 4, while the broadening of Raman lines due to the effects of intermolecular forces is taken up in Chapter 5.

Download or read book Coherent Anti-Stokes Raman Spectroscopy (CARS) written by and published by . This book was released on 1993 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coherent Anti-Stokes Raman Spectroscopy (CARS) has been accepted as a very useful tool in combustion diagnostics. CARS is an optical technique in which two powerful laser beams are brought to a focus over a very small region in a medium usually a flame. This produces an output laser-like beam arising from a specific interaction of the laser radiation with the molecules of the gases in the flame and the spectral characteristics of this beam contains information about the temperature and species present in the focal volume. The relevant information from the CARS spectra can be extracted only by comparing it with theoretically calculated spectra. A complex software package was developed for generating the theoretical CARS spectra and for analyzing the experimental spectra. This report describes the tasks undertaken to enhance the capabilities of the existing CARS software package with the aim of detecting species such as NO and O2.

Book Synopsis Analysis for Coherent Anti-Stokes Raman Spectroscopy (CARS). by : Herschel Weil
Download or read book Analysis for Coherent Anti-Stokes Raman Spectroscopy (CARS). written by Herschel Weil and published by . This book was released on 1980 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupled differential equations have been formulated which model the generation of coherent anti-Stokes Raman radiation in molecular gases. The equations include not only the basic term which involves the coherent interaction of incident pump and idler (Stokes) waves to generate the anti-Stokes radiation, but also include additional terms which model other radiation and absorption processes, both stimulated and coherent, which occur simultaneously. These are important in determining saturation effects due to population depletion of the lowest energy level. Other effects have also been considered. These are a finite idler beam bandwidth (simultaneous excitation of more than one vibration frequency) a quasi-monochromatic idler beam slightly off the true Stokes frequency; laser pulse shape; modification of the result for different rotational levels. A number of different computer codes have been developed to solve the equations at different levels of complexity. With them numerical investigation of the effects of various physical factors on saturation was carried out. Some of the results are presented graphically. (Author).

This book was released on 1979 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coherent anti-Stoke Raman spectroscopy (CARS) investigations in sooting, laminar and turbulent, propane-fueled diffusion flames are reported. For a 5320 A pump wavelength, using a frequency-doubled neodymium laser, interferences can occur at very high soot densities. For N2 CARS, there are both incoherent and coherent components to the interference. The incoherent interference arises primarily from anti-Stokes fluorescence from C2 excited by Stokes laser absorption. The C2 is created by the laser vaporization of soot particulates, shown to occur even on a nanosecond time scale. The coherent interference arises most probably from electronically-resonantly enhanced wave mixing in the C2. Fortunately, neither interference is very large. By proper experimental design, interference-free CARS spectra from flame N2 can be obtained even at high soot densities. CARS signatures from N2 have been employed to map the temperature field with high spatial precision throughout a small, luminous, highly sooting, laminar propane diffusion flame. Single pulse (approx, 10 nanosecond) CARS thermometry has been demonstrated in various regions of a highly swireld, turbuelnt propane diffusion flame. Based upon these investigations, CARS continues to appear very promising for diagnostic applications to practical combustion sources. (Author).

Book Synopsis Coherent Anti-stokes Raman Scattering (CARS) Optimized by Exploiting Optical Interference by : Wang, Xi
Download or read book Coherent Anti-stokes Raman Scattering (CARS) Optimized by Exploiting Optical Interference written by Wang, Xi and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work is to study the interference between the coherent nonresonant four-wave-mixing (FWM) background and the Raman-resonant signal in the coherent anti-Stokes Raman spectroscopy (CARS). The nonresonant background is usually considered as a detriment to CARS. We prove that the background can be exploited in a controllable way, through the heterodyne detection due to the interference, to amplify the signal and optimize the spectral shape of the detected Raman signal, and hence enhance the measurement sensitivity. Our work is based on an optimized CARS technique which combines instantaneous coherent excitation of multiple characteristic molecular vibrations with subsequent probing of these vibrations by an optimally shaped, time-delayed, narrowband laser pulse. This pulse configuration mitigates the nonresonant background while maximizing the resonant signal, and allows rapid and highly specific detection even in the presence of multiple scattering. We investigate the possibility of applying this CARS technique to non-invasive monitoring of blood glucose levels. Under certain conditions we find that the measured signal is linearly proportional to the glucose concentration due to optical interference with the residual background light instead of a quadratic dependence, which allows reliable detection of spectral signatures down to medically-relevant glucose levels. With the goal of making the fullest use of the background, we study the interference between an external local oscillator (nonresonant FWM field) and the CARS signal field by controlling their relative phase and amplitude. Our experiment shows that this control allows direct observation of the real and imaginary components of the third-order nonlinear susceptibility (x(3)) of the Raman sample. In addition, this method can be used to amplify the signal significantly. Furthermore, we develop an approach by femtosecond laser pulse shaping to precisely control the interference between the Raman-resonant signal and its intrinsic nonresonant background generated within the same sample volume. This technique is similar to the heterodyne detection with the coherent background playing the role of the local oscillator field. By making fine adjustments to the probe field shape, we vary the relative phase between the resonant signal and the nonresonant background, and observe the varying spectral interference pattern. These controlled variations of the measured pattern reveal the phase information within the Raman spectrum, akin to holographic detection revealing the phase structure of a source.
