Descripción

General description

Dimethyl sulfoxide-d₆ (DMSO-d₆) is a deuterated NMR solvent. 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.
