Chloroform raman

Web1 Introduction. Raman spectroscopy is a widely used analytical tool for a range of applications. 1-3 In particular, Raman spectroscopy is useful for interrogation of biological samples, because of its insensitivity to water molecules and a working range within the visible and near-infrared regions. 4 Because the chemical fingerprints of biological … WebChloroform-d (Deuterochloroform, CDCl 3) is a deuterated derivative of chloroform. It contains 1% (v/v) TMS (Tetramethylsilane, added as a stabilizer). Quantitative infrared spectral investigations of carbon-deuterium stretching bands of chloroform-d in various organic solvents have been reported.
