Direct identification of product CH2SH+/CH3S+ structures in the dissociation of CH3CH2SH+ and CH3SCH3+ via collisional activation
We report an experiment on the structural identification of CH3SC/CH2SH+ formed in the collision-induced dissociation reactions of CH3SCH3+ (CH3CH2SH+) + Ar. We found that CH2SH+ is the dominant ion formed in the collision-induced dissociation of CH3CH2SH+, while CH3S+ is produced in abundance along with CH2SH+ in the collision-induced dissociation of CH3SCH3+. The results are attributed to the non-statistical nature of the dissociation processes.
