Dimethilsulfoxide may give signal, event at low concentrations. This may be counteracted using a blank : all reactive including DMS without the agent studied (the reactive which is dissolved in DMS).

The broad signal at ~3.3 ppm in the proton spectrum is due to traces of moisture (water).

May you give additional details about the additional signals in carbon spectrum? I.e. chemical shifts, multiplicity...
