The mass spectra of 3,8‐dichloro‐11H‐dibenzo[c,f] [1,2]diazepine, the corresponding diazepin‐11‐01 and diazepin‐11‐one and their dihydro and N‐oxide derivatives have been recorded. The most important fragmentation of the molecular ions of all diazepines studied was an initial loss of m / e 28, with further fragmentation depending on the 11‐substituent. No general pathway was observed for the corresponding N‐oxides and dihydro compounds.
