: This report presents the ion series of mass spectra for eight homologues of 2,4,6-tris(perfluoroalkyl)-1,3,5-triazines from NIST libraries, including the ion series of two isomers: triazine (C 3 F 7 ) 3 C 3 N 3 with symmetrical substituents C 3 F 7 and triazine (CF 3 ) 2 C 3 N 3 (C 7 F 15 ) with unsymmetrical substituent C 7 F 15 . The influence of molecular weight of substituents and their symmetry on fragmentation of 1,3,5-triazines is discussed. Using [(CF 3 ) 3 CO] 3 C 3 N 3 homologue with oxaperfluoroalkyl substituents as an example, the effect of (CF 3 ) 3 C groups and oxygen atoms on fragmentation is discussed
本文报道了NIST文库中8个2,4,6-三(全氟烷基)-1,3,5-三嗪类同系物的离子谱，包括具有对称取代基c3f7的三嗪(c3f7) 3c3n3和具有不对称取代基c7f15的三嗪(cf3) 2c3n3 (c7f15)的离子谱。讨论了取代基的分子量及其对称性对1,3,5-三嗪断裂的影响。以含全氟烷基取代基的[(CF 3) 3co] 3c3n3同源物为例，讨论了(CF 3) 3c基团和氧原子对断裂的影响
