✦ Synopsis
The mechanism for unimolecular fragmentation of the methyl nitrite radical cation, CH,ONO+, has been determined by mass spectrometric techniques applying deuterium and I80 labelling. It could be unambiguously concluded that methyl nitrite radical cations possessing low internal energy fragment exclusively to the hydroxy-methyl cation. The recent proposal of a quantummechanical tunneling mechanism forcing an alternative reaction, leading to D2NO+, on deuterium labelling of the methyl nitrite radical cation could unequivocally be excluded.
