Matrix Ir Spectra

We report an extensive computational and spectroscopic study of several fluoropyridine–HCl complexes, and the parent, pyridine-HCl system. Matrix-IR spectra for pentafluoropyridine–HCl, 2,6-difluororpyridine–HCl, and 3,5-difluororpyridine–HCl in solid neon exhibit shifts for...

Proton Dynamics

The work outlines general ideas on how the frequency and the intensity of proton vibrations of X–H×××Y hydrogen bonding are formed as the bond evolves from weak to maximally strong bonding. For this purpose, the Raman spectra of different chemical compounds with moderate, strong, and extremely strong hydrogen bonds were obtained in the temperature region of 5 K–300 K. The dependence of the proton vibrational frequency is schematically presented as a function of the rigidity of O-H×××O bonding. The problems of proton dynamics on tautomeric O–H···O bonds are considered. A brief description of the N–H···O and C–H···Y hydrogen bonds is given.
