[Studies of laser Raman spectra of ZnCl2 solution effected by environmental light]

The laser Raman spectra influenced by environmental light were studied in the determination of ZnCl2 solution. The environmental light included the natural light from outdoors and the light from indoor fluorescent. The results show that different influences on the laser Raman spectra of ZnCl2 solution can be produced in different environmental light. There were some characteristic spectral lines, minus peaks or sharpened peaks. These influences cannot be ignored. The determinations of laser Raman spectra must be made in darkroom or in the sheathing or mantle etc.
