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. [ 2] WebOct 1, 2024 · The physical properties of their semisynthetic (non-)deuterated products are compared in a solution using 1 H NMR, visible absorption, ... Its 1 H NMR spectrum in deuterated chloroform showed that the 3-acetyl singlet peak of 1c at 3.30 ppm disappeared (Fig. S9) and a new methyl resonance at 2.13 ppm was observed (Fig. S6).
