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.
这项工作概述了关于随着X-H···Y氢键从弱键发展到最强键，质子振动频率和强度是如何形成的一般观点。为此，在5 K至300 K的温度范围内获得了具有中等、强和极强氢键的不同化合物的拉曼光谱。质子振动频率的依赖性被示意性地表示为O-H···O键刚性的函数。考虑了互变异构O-H···O键上质子动力学的问题。对N-H···O和C-H···Y氢键进行了简要描述。
