Annotation The Raman spectra temperature dependences of water in the range 2900-3700 cm – 1 were investigated. This is the region of the valence symmetric and asymmetric bands vibrations of water OH-groups. The cluster model of water which consists of small clusters (from one to six molecules in the formation) was used. The relative cluster contribution in the water spectrum was found. The low frequency region 2800-3300 cm – 1 is formed mainly by cluster types (H2O)3, (H2O)4, (H2O)5, (H2O)6 and the high frequency region 3300-3800 cm – 1 is formed mainly by cluster types (H2O)2, (H2O)3, (H2O)4. Cluster type (H2O)3 dominates at the temperature 20 °C and this dependence don’t change extremely within all measured temperature range 0-95 °C.
