irradiation with white light, the predominant conformation of the 1,3-diphenyl-2-aza-allyl carbanion is changed from trans,trans to cis,trans. The kinetics of the reverse dark reaction have been studied. The loose ion pairs with lithium, sodium, and potassium all have very similar Arrhenius parameters; the tight ion pairs with sodium and potassium, but not with lithium, have smaller values of both E and A
在白光照射下,1,3
-二苯基-2-氮杂-烯丙基烯丙基的主要构象从反式,反式变为顺式,反式。已经研究了反向暗反应的动力学。具有

钾而不是与
锂的紧密离子对具有较小的E和A值。电子光谱取决于构象,并且在某种程度上取决于离子对的性质。
