✦ Synopsis

The loss of hydrogen chloride (HCl) is one of the main fragmentation processes in the molecular ions of o-, m-and p-chlorophenols in the metastable time window. By investigation of D-labeled compounds, it could be established that the eliminated HCl molecule contains only the hydroxylic hydrogen atom, not other benzene ring hydrogen atoms. This process is rationalized by the so-called 'ring-walk' mechanism for a chlorine atom.
