Modern Optical Spectroscopy By William W. Parson -------------------------------------------------------------------------------- Publisher: Springer Number Of Pages: 522 Publication Date: 2007-01-24 ISBN-10 / ASIN: 354037535X ISBN-13 / EAN: 9783540375357 Binding: Hardcover -------------------------------------------------------------------------------- Product Description: Modern Optical Spectroscopy gives clear explanations of the theory of optical spectroscopic phenomena and shows how these ideas are used in modern molecular and cellular biophysics and biochemistry. The topics covered include electronic and vibrational absorption, fluorescence, resonance energy transfer, exciton interactions, circular dichroism, coherence and dephasing, ultrafast pump-probe and photon-echo spectroscopy, single-molecule and fluorescence-correlation spectroscopy, Raman scattering, and multiphoton absorption. The explanations are based on time-dependent quantum mechanics and are sufficiently thorough and detailed to be useful for people working in the field. Because it starts from first principles, the text also will be accessible to readers with little prior training in quantum mechanics. Extra details and sidelights are set off in boxes. Numerous figures illustrate the theoretical expressions or explain experimental techniques. -------------------------------------------------------------------------------- Summary: 20/20 Vision For Theoretical Treatment of Optical Spectroscopy Rating: 5 As a biochemist who uses electronic spectroscopy as a tool for solving biochemical problems I have come to appreciate certain deficiencies in my academic training. Aspects of quantum mechanics and molecular orbital theory that are not normally a core part of biochemistry curricula are clearly important for understanding and interpreting experimental findings obtained by spectroscopic methods such as ultraviolet absorbance and circular dichroism. Perhaps the most useful text that I've found to help me come to grips with the subject is the 1962 classic "Theory and Applications of Ultraviolet Spectroscopy," by Jaffé and Orchin. Here the focus is on organic chemistry, but William W. Parson has now provided a deeper treatment of the theory that draws examples from biophysics and biochemistry. Parson has filled in the many gaps that appear to have emerged in the discipline in the past 45 years. For me it has been a revelation to see explanations from first principles for the origins of the Rosenfeld equation and the point-dipole approximation, for example. Parson makes an interesting connection between Förster and exciton theories as variations on a common theme of excited state delocalization, but at greater and shorter distances, respectively. One criticism is that the discussion of the exciton effect seems to be limited entirely to the degenerate case where chromophores having identical energies interact. I would like to have seen the non-degenerate case discussed as Harada and Nakanishi treated it previously in Chapter 10 of their treatise on circular dichroism. I have not had a chance to read Parson's entire book, but what I have consulted has been gripping and easy to comprehend - the appendices on vectors, matrices, and Fourier transforms have certainly helped me to overcome some of my own deficiencies with the mathematics. Ultimately, Parson strives to create a physical picture that mathematics only serves to summarize, which is precisely what I want to know. I suspect that "Modern Optical Spectroscopy" will become an essential reference for experimentalists who seek to be quantitative in interpreting their observations derived from a wide range of electronic spectroscopic methods. http://mihd.net/v6n0r5/__1d6a0bd__via_gigapedia.info__.html |
