用无明显拖尾的TEACO_2激光强脉冲“超激发”氟里昂_(123)分子(CF_3CHCl_2和CF_3CDCl_2),使其形成很高激发态。在一定条件下,在离解过程中,这种分子主要表现为具有较高键能的C—C键被打断,其主要产物是C_2F_4和丙二烯及其取代物,而具有最低键能的C—Cl键的开裂却很少,离解产物的相对产量与激光能流密度的关系曲线指出,氟里昂_(123)分子内的V-V能量转移具有非随机化行为。 Strong pulsed TEACO_2 laser pulse “super excited” Freon _ (123) molecules (CF_3CHCl_2 and CF_3CDCl_2) to form highly excited states. Under certain conditions, during the process of dissociation, this molecule is mainly characterized by the C-C bond with a high bond energy being interrupted, the main products of which are C 2 F 4 and allenes and their substitutions, and the lowest bond energy The C-Cl bond cracking is rare, and the relationship between the relative yield of dissociation products and the laser fluence shows that the VV energy transfer in freon-123 has a non-randomized behavior.
