Deuterated chloroform physical properties

WebChloroform-d (deuterochloroform, CDCl 3) is a deuterated NMR solvent containing 0.1 % (v/v) TMS (tetramethylsilane). It is useful in NMR-based research and analyses. It may be synthesized by reacting trichloroacetophenone and sodium deuteroxide. [ 1] The influence of the number of pulses on its multiphoton decomposition (MPD) has been studied.
