The adaptation and construction of an environmental chamber suitable for FT-Raman spectroscopy is described for the recording of Raman spectra of specimens at temperatures from 25 to 125 °C while exposed to different controlled synthetic atmospheric conditions. Test spectra were obtained from sulfur to illustrate the stability and applications of the system. The α rhombic/β monoclinic phase change in sulfur was monitored as a function of time, and bands sensitive to this phase change have been identified.

In the analytical environment, spectral data resulting from analysis of samples often represent mixtures of several components. Extraction of information about pure components of these kinds of mixtures is a major problem, especially when reference spectra are not available or when unstable intermediates are formed. Self-modeling multivariate mixture analysis has been developed for this type of problem. In this paper two examples will be used to show the potential of this technique coupled with FT-Raman spectroscopy to elucidate reaction mechanisms and to follow in situ the kinetics of chemical transformations.
