General description
Dimethyl sulfoxide-d6 (DMSO-d6) is a deuterated NMR solvent containing 0.1%(v/v) TMS (tetramethylsilane). It undergoes photodissociation to generate CD3 radical photoproducts, which have been analyzed by infrared diode laserabsorption spectroscopy. Dissociation dynamics of DMSO-d6 at 193nm was examined using photo fragment translational spectroscopy method.
Application
Dimethyl sulfoxide-d6 may be used as an NMR solvent for 1H and 13C NMR experiments.
