Description
A resonance representation of the electronic structure of S-nitrosothiols as a combination of the conventional R-S-N=O structure, a zwitterionic structure R-S+=N-O-, and a RS-/NO+ ion pair is proposed. The resonance forms are employed to predict and rationalize the structural and conformational properties of RSNOs, their interaction with Lewis acids, and their overall chemical reactivity.
