Spectroscopic techniques and hindered molecular motion

Description:

"The theory of hindered motions of small molecules and molecular fragments in crystals and liquids allows one to obtain detailed knowledge of both the crystal structure and the dynamical behavior of molecules. Application of the theory to describe such phenomena as NMR relaxation rates and spectral line broadening expands the power of many spectroscopy techniques. The author compares this theoretical approach with recent experimental results. Specific topics covered include the extended angular jump model, angular autocorrelation functions, dielectric and optical spectroscopy applications, and nuclear magnetic resonance spin-lattice relaxation applications"-- "Determining the nature of intra- and inter-molecular interactions as well as the character of molecular motion is one of the key problems of condensed state physics. The scope of this monograph is restricted to small molecules and molecular fragments, such as N2, HC1, CO2, CH4, H2O, NH4, BeF4, NH3, CH3, C6H6, SF6 and other symmetrical atomic formations that exhibit local hindered motion in molecular condensed media: molecular and ionic crystals, molecular liquids, liquid crystals, polymeric solids, and biological objects"--
