Abstract.
Raman spectra of water within the temperature range 20 to 3 C were
investigated. Best of all, the complex shape of the obtained spectra was approximated by
four (or five) Gaussian-shaped peaks with their positions 3070, 3230, 3440, 3600 (and
3650) cm –1 . The most intensive constituents were 3230 and 3440 cm –1 lines, their total
contribution to the Raman spectrum of water is higher than 90%. These lines are the most
sensitive to the temperature, too. When the temperature decreases from 20 down to 3 C,
the positions of these peaks were shifted from 3232 to 3224 cm –1 and from 3441 to
3434 cm –1 , respectively; and the intensity of 3230 cm –1 line was increased approximately
by 14% in its magnitude.
Keywords: Raman spectra, water structure, temperature, pressure.
