## Abstract The mass spectrometric behaviour of some 2‐hydroxymethyl‐3,4,5,6,7,8‐hexahydro‐2__H__‐1‐benzopyran‐5‐ones is described and discussed with the aid of exact mass measurements, linked scans, labelling experiments and low electron energy measurements. The unusual presence of abundant [MH~3
Two theoretical models, a reorganization model and an activation model, are presented for accurately determining the energy barrier of the type Ž . 2qr3q M H O of the transition-metal complexes in the electron-transfer process. Ab initio 2 6 Ž . 2qr3q calculations are carried out at UMP2r6-311G leve
