RESEARCH REPORT ON MEASURING THE RAMAN-SPECTRA OF TEMPERATURE-SENSITIVE SOLID SAMPLES

The Raman spectra of temperature-sensitive samples are often difficult to record because of the significant temperature rises (up to 40 degr ees C) experienced when using relatively low (125 mW) laser powers. Th ese effects can be minimised by using nujol mulls and pressed disks si milar to those commonly employed for infrared analysis. This is illust rated by the use of a series of highly coloured samples whose further analysis allows the optimised sampling parameters to be presented.
