Vibrational spectra of liquid water contain a wealth of information about its structure and dynamics but there are no generally acknowledged interpretation of their band profiles, unfortunately. We have tried to calculate them taking into account onl

Analytical description of the spectra of two coupled vibrational modes in the case of the homogeneous broadening of the interacting bands is proposed. Inter alia, the intrinsic overtone's intensity is taken into account in the course of the analysis

A general case of interaction between two oscillators of statistically distributed frequencies has been studied. The interaction between fundamental and overtone vibrations (Fermi resonance) can be a special case. The feasible, non-zero original inte

The ability of water molecules to form a three-dimensional network of hydrogen bonds basically determines both the intrinsic structure and unique properties of this liquid and also a character of interactions with other molecules. However, the depend

A principle to design the multi-parameter potentials of hydrogen bonding is proposed and developed. Based on fluctuation theory, they provide the description of temperature evolution of the shape of OH vibrational spectra of liquid water molecules. A

The infrared spectra of HOD molecules in liquid water are calculated at constant density over the temperature range of 10 to 400°C from the statistical distributions of the vibration frequencies of water OH-groups determined previously from the expe
