title: [On singularities of molecular relaxation in water solutions].
abstract: In this paper, we analyzed spectra of liquid water and water solutions in a frequency domain, characteristic of the collective dynamics of water molecules (from 0 to 200 cm(-1)). Particular attention is paid to the relaxation processes, one of which is observed in the terahertz region of the spectrum (approximately 5-50 cm(-1)). The physical essence of this process at the molecular level is still unclear. Based on data obtained this process is strongly suggested to interpret as a monomolecular relaxation of unbound water molecules.
