The mass spectra of twenty‐one s ‐triazines have been interpreted. An unusual feature noted in the spectra of some of the compounds is transfer of a hydrogen atom of a side chain to a nitrogen atom of the s ‐triazine ring; two such shifts are suggested as a rationale for the unusual loss of nitrogen from a hydrazide derivative. The fragmentation of triamino‐ and some diamino‐ derivatives indicates that imino tautomers play a significant role. The spectra of aryldiamino s ‐triazines suggest that the site of a substituent in the aryl ring is important in some cases in directing the decomposition; some transitions have been rationalised on the basis of the juxtaposition of the substituent in relation to a nitrogen atom of the heterocyclic ring.
