Anharmonic model of liquid dynamics
I.L.Kondratiev

 Far infrared absorption measurements for disperse particles of distilled water were performed in the frequency range from 50 cm^−1 to 650 cm^−1 with Fourier Transform Infrared Spectrometer (FTIR) at every 3 °C from − 42 °C to 30 °C . The obtained spectra of water were apparently a sum of overlapping absorption peaks. The curve fitting procedure was applied to them. At least three peaks should be assumed to explain the 180 cm^−1 band contour. The temperature dependence of the unstable translational mode fraction was calculated from the properties of the 180 cm^−1 band main peak. It proved to be in agreement with the results obtained from the viscosity and self-diffusion data. 
The Fourier Transform Infrared Spectrometer was improved and computerized. A method of preparing the samples employing ultrasonic dispersing was designed. Temperature control system was reformed which made possible the measuring at exact temperature in the wide range. Special software for controlling facilities, data acquisition and manipulating was created using LabVIEW.
