氢原子价态振动频移的本质

Nature of the Frequency Shift of Hydrogen Valence Vibrations

I. V. Zhyganiuk, M. P. Malomuzh

摘要:

本文研究了水分子中氢原子价态振动由于与邻近分子相互作用而发生频移的物理本质。与分子多极矩有关的静电力被认为对分子间相互作用起主要作用。在两个相邻分子形成二聚体的情况下计算频移。所得到的结果是在定性协议与观察到的水蒸气,六角冰,和液态水,以及醇的水溶液的频率偏移。这一事实证明了氢键的静电性质,氢键用于描述水分子间相互作用的具体特征和后者的宏观性质。

英文摘要:

The physical nature of a frequency shift of hydrogen valence vibrations in a water molecule due to its interaction with neighbor molecules has been studied. Electrostatic forces connected with the multipole moments of molecules are supposed to give a dominating contribution to the intermolecular interaction. The frequency shift was calculated in the case where two neighbor molecules form a dimer. The obtained result is in qualitative agreement with the frequency shifts observed for water vapor, hexagonal ice, and liquid water, as well as for aqueous solutions of alcohols. This fact testifies to the electrostatic nature of H-bonds used to describe both the specific features of the intermolecular interaction in water and the macroscopic properties of the latter.
