ABSTRACT
The Raman spectra of different concentrations of NaOH solutions have been successfully obtained at normal pressure by cooling. The results indicate that the icing point and the ice phase transition temperature of NaOH solutions decrease with increasing concentrations. Particularly, the different concentrations (2, 4, 6 or 8 and 12M) take place the liquid- III- Ih, liquid- V- Ih, liquid- VI- XV and liquid- IX- VI phase transition, respectively. In addition, the three peaks of around 3524, 3580 and 3624cm-1 appear spectra of the NaOH solutions at low temperature.
