Mass spectral fragmentations of nine benzodiazepin derivatives were examined by exact mass measurement and by metastable ion analysis. Under electron impact conditions, all compounds give rise to a molecular ion and ions of m / z 160, 159, 147, 131, 104, 77, 56, 41, and 39. Key fragmentation pathways are discussed for these ions.
