Book Synopsis Excited States in Quantum Chemistry by : Cleanthes A. Nicolaides
Download or read book Excited States in Quantum Chemistry written by Cleanthes A. Nicolaides and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is undoubtedly true that much of the progress in the quant~m theory of matter is due to the remarkable success of the independent particle model (IPM)--especially in describing ground states. However, the accurate experimental results of the last 10 years or so, on a variety of spectroscopic phenomena and chemical processes which involve the Excited State, and the related failure of the IPM to reproduce accurately--in many cases, even qualitatively--the observed data, have sent to theorists a clear message: There is need to create and/or apply general and useful approaches to the many-electron problem of the excited state which go beyond the IPM, treat electron correlation and relativity and explain or predict all relevant physical or chemical information with consistent accuracy. This book contains articles devoted mainly to some of the most important new developments in Quantum Chemistry concerning the theoretical foundations and the computational implementation of many-body approaches to the quantitative and detailed under standing of the electronic excited states of atoms, molecules and solids. Furthermore, it contains experimental and pheno menological articles on Photoelectron and Auger spectroscopy, Lifetime measurements and Organic Photochemistry. In combination or individually, these articles constitute a good description of some current theoretical and experimental work on the electronic structure and spectroscopy of atoms, molecules, polymers, surfaces, metal oxides and amorphous solids.

Available in PDF, EPUB and Kindle. Book excerpt: Of all major branches of organic chemistry, I think none has undergone such a rapid, even explosive, development during the past twenty-five years as organic photochemistry. Prior to about 1960, photochemistry was still widely regarded as a branch of physical chemistry which might perhaps have oc casional applications in the generation of free radicals. Strangely enough, this attitude to the subject had developed despite such early signs of promise as the photodimerization of anthracene first observed by Fritzsche in 1866, and some strikingly original pioneering work by Ciamician and Silber in the early years of this century. These latter workers first reported such varied photo reactions as the photoisomerization of carvenone to carvone camphor, the photodimerization of stilbene, and the photoisomerization of o-nitrobenzal dehyde to o-nitrosobenzoic acid; yet organic chemists continued for another fifty years or so to rely almost wholly on thermal rather than photochemical methods of activation in organic synthesis-truly a dark age. When my colleagues and I first began in the 1950s to study the synthetic possibilities of photoexcitation in the chemistry of benzene and its derivatives, virtually all the prior reports had indicated that benzene was stable to ultraviolet radiation. Yet I think it fair to say that more different types of photoreactions than thermal reactions of the benzene ring are now known. Comparable growth of knowledge has occurred in other branches of organic photochemistry, and photochemical techniques have in particular made possible or simplified the synthesis of numerous highly strained organic molecules.

This book was released on 2019 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemical reactions provide a complementary strategy for the synthesis of complex organic molecules as it often involves multiple bond formation in a single step. However, use of organic photoreaction as a common tool in synthesis is limited due to challenges associated with controlling their excited state properties. Altering the molecular framework has the potential to alter their excited state features opening new reactive pathways. This requires in depth understanding of reactivity and excited state dynamics. This dissertation details an effort to engineer new excited state reactions of organic molecules. Fundamentals of organic photochemistry and various strategies that were developed in this field are discussed in the first chapter. It details concepts related to organic photoreactions and asymmetric photochemical transformations, which are known to be quite challenging due to short life time and high energetics of the reactive excited states. The chapter details various methodologies that are developed and successfully implemented for controlling photochemical reactions. Second chapter describes photocycloaddition of an excited alkene to a carbonyl group. Due to the difference in the nature of orbital that initiates the cycloaddition, the reaction was labeled as Transposed Paternò-Büchi reaction. The strategy developed in this chapter is different from normal Paternò-Büchi, where an excited state carbonyl functionality adds to a ground state alkene. In-depth investigations were carried out to decipher the excited state in the reaction pathway with a likely mechanistic rationale. Chapter three details the photocycloaddition of excited alkenes with statistical and nonstabilized imines. This newly uncovered reaction was labeled as Aza Paternò-Büchi reaction. This new reaction was deciphered using photophysical studies. The reactive modes were This new reaction was deciphered using photophysical studies. The reactive modes were Fourth chapter details entropic effects as a tool to control chemoselectvity involving intramolecular [2+2] vs [3+2]-photocycloaddition. The physical properties for entropic control were deciphered due to [2+2] and [3+2] cycloaddition.
