Kinetics and mechanisms of unimolecular gas-phase γ-hydrogen rearrangements of aliphatic aldehydes at times of the order of 10 picoseconds and longer following field ionisation
Abstract
Evidence is presented that the γ-hydrogen transfer in the decomposition processes of aliphatic aldehydes referred to as McLafferty rearrangement occurs as a discrete step at times longer than ca. 20ps following field ionisation.
