Product ion distributions for the reactions of NO+ with some N-containing and O-containing heterocyclic compounds obtained using SRI-TOF-MS

- Reactions of 15 heterocyclic compounds with NO+ in SRI-TOF-MS were investigated.
- Charge transfer was the dominant ionization mechanism generating M+ parent cation.
- Stable fractions of the adduct ion NO+M were also seen for pyridines and pyrimidines.
- Lower E/N values prevent fragmentation and promote the formation of NO+M ions.
