Leland B. Gee, Hongxin Wang and Stephen P. Cramer 9 Nuclear resonance vibrational spectroscopy 9.1 Introduction 9.1.1 Mössbauer effect In a Mössbauer experiment, the intensity directly scales with fLM, such that the observed cross section, σN, is reduced from the total cross section according to σ(0) ~(π/2) σN fLM [6]. However, there is a “sum rule” that states that the integrated cross section for a nuclear transition remains constant [7]. So, where does this missing intensity go? The missing intensity is in the “recoil fraction,” 1 – fLM, where nuclear

_ Wet Surface Vibrational Spectroscopy Experiments In recent years, there have been important developments in vibrational spectroscopic techniques applicable to studies of the wet interfaces which surround us in nature and in technology. Methods that can provide vibrational spectroscopic information about monolayers at surfaces are powerful tools in revealing the molecular basis of the observed macroscopic behavior of such systems. Surface enhanced Raman spectroscopy (SERS), which gives remarkable enhancement of typically weak Raman scattering, was at first

Vibrational spectroscopy is an ideally suited tool for the study of solute hydration. Nevertheless, water is commonly considered by spectroscopists a difficult solvent to work with. However, by using the isotopic dilution technique, in which a small amount of D2O is introduced into H2O or vice versa with formation of semiheavy water (HDO), many technical and interpretative problems connected with measurement of infrared spectra of water may be circumvented. Particularly, the isotopic decoupling of stretching vibrational modes greatly simplifies interpretation of the spectra. Systematic studies conducted in several laboratories since the 1980s up to the present day have provided a vast amount of data, concerning mainly ionic hydration. Many of these experiments have been performed in our laboratory. The analysis method we applied is based on the quantitative version of the difference spectra technique and allows separation of the spectrum of solute-affected HDO from the bulk solvent. This review illustrates the development of vibrational spectroscopy of HDO and spectral analysis methods over the years, as well as summarizes the results obtained for ionic and nonionic solutes, including some general hydration models formulated on their basis.
