The gas phase chemistry of the methyl carbamate radical cation H2NCOOCH+3: isomerization into distonic ions, hydrogen-bridged radical cations and ion—dipole complexes

The unimolecular chemistry of the methyl carbamate radical cation, H2NCOOCH+3, 1, has been investigated by a combination of mass spectrometry based experiments (metastable ion (MI), collisional activation (CA), colision-induced dissociative ionization (CIDI), neutralization—reionization (NR) spectrometry, 2H, 13C and 18O isotopic labeling, appearance energy (AE) measurements), and ab initio molecular orbital calculations, executed at the …
