The solidified residue is homogeneous by gas chromatography, and its infrared and nuclear magnetic resonance spectra and gas chromatogram are identical to those of recrystallized authentic benzyl sulfide. The product may be recrystallized in ca. 25 ml. of absolute ethanol to yield colorless plates, m.p. 47-48° (literature3 m p 50°), which give a satisfactory combustion analysis... [Pg.142]

Modem structural chemistry differs from classical structural chemistry with respect to the detailed picture of molecules and crystals that it presents. By various physical methods, including the study of the structure of crystals by the diffraction of x-rays and of gas molecules by the diffraction of electron waves, the measurement of electric and magnetic dipole moments, the interpretation of band spectra, Raman spectra, microwave spectra, and nuclear magnetic resonance spectra, and the determination of entropy values, a great amount of information has been obtained about the atomic configurations of molecules and crystals and even their electronic structures a discussion of valence and the chemical bond now must take into account this information as well as the facts of chemistry. [Pg.4]

A critical issue crossing all boundaries is the interaction of matter and radiation. Spectroscope experiments are used as both structural and dynamic probes and to initiate chemical processes (as in photochemistry and laser-induced chemistry), and such experiments must be understood theoretically. There are also many subfields of theoretical chemistry—for example, biomedical structure-activity relationships, the molecular theory of nuclear magnetic resonance spectra, and electron-molecule scattering—that fit into two or more of the areas listed. [Pg.1241]

In every case we have emphasized that the distortions are not without effect on the covalent character of the bonds involved. We have tried to show that the tendency to distortion could often have an electrostatic origin, and hence that other than stereochemical arguments must be used in determining the degree of covalency both in distorted and in undistorted complexes. Such methods include the study of antiferromagnetic interaction, nuclear magnetic resonance spectra, and paramagnetic resonance spectra. [Pg.53]

It is of course clear that properties other than UV spectra are valuable as reporting properties such properties as electron spin and nuclear magnetic resonance spectra and fluorescence yield valuable information about the environment in the protein. [Pg.177]
