2.(1) the respective fragments m/z 176, 191, 192, 193, 161 are formed from molecular ion M~+ on the fragmentation mechanism via various cleavage modes; (2)the base peak at m/z 191 is formed with the loss of a neutral molecule via the ortho effect; (3) the base peak m/z 191 may further be cleaved to form fragments m/z 147, 132, 91; (4) the cleavage of C--N bond in si.本文对2,6—双(二甲胺甲基)—4—乙基酚二盐酸盐这一对称型分子进行了精确质量和亚稳测定,证实了:(1)由分子离子M~+经过多种裂解方式,分别形成相应碎片m/z 176、191、192、193、161的裂解机理;(2)基峰m/z 191是由M~+通过邻位效应失去HN(CH_3)_2中性分子形成的;(3)基峰m/z 191可进一步裂解,通过多种途径形成m/z 147、132、91相应碎片;(4)苯环侧链胺基中C—N键的开裂与非对称型分子相似,而与脂肪胺中C—N键稳定不开裂的过程截然相反。
3.Results show that the atom N is most likely to dissociate in neutral fragment forms of NH2,HCN,HCN2,N3 and N4,while the fragmentation mechanisms are the cleavage of C—N and N—N and the rearrangment.根据质谱图中碎片离子的信息,总结了四氮烯的裂解途径,发现四氮烯裂解时主要有NH2、HCN、HCN2、N3、N4中性碎片的丢失,推测它的裂解机理是C—N、N—N键的断裂反应和分子内重排反应;同时发现四唑环碎片离子m/z68。
