Dissociative electron attachment to gas-phase N-methylformamide

- The DEA to NMF produces CN−, OCN−, NH2−, O−, HCO−, and NH−, similarly to formamide.
- Newly observed anions for NMF are: CH3NHC(O)−/CH3NC(O)H−, CH3NH−, CO−, and CH3−.
- The CH3NH− and HCO− anions indicate peptide bond cleavage occurs upon DEA to NMF.
- The CH3 group of NMF lowers the thermodynamic thresholds to CN− and OCN− formation.
- Site-selective H loss from the aldehyde or amide group occurs but not from CH3.
