氮分子的第一电子激发态N_2(A,~3∑_u~+)可以在流动反应管中用Ar(~3P_(2,0))与N_2(X)之间的能量转移反应产生,由于它与基态之间的跃迁是禁戒跃迁,放N_2(A)的寿命相当长,约为2秒,M_2(A)与惰性气体及N_2(X)之间的淬灭速率常数都很小,因而它是一个优良的贮能分子。这些能量可以用来研究一些离解激发转移反应或激发转移反应。这类反应除了在激光中 The first electron excited state N 2 (A, ~ 3Σ_u ~ +) of nitrogen molecule can be generated by the energy transfer reaction between Ar (~ 3P_ (2,0)) and N_2 (X) in the flow tube. The transition between the ground state and the ground state is an forbidden transition. The life span of N_2 (A) is quite long, about 2s. The quenching rate constant between M_2 (A) and inert gas and N_2 (X) So it is an excellent energy storage molecule. These energies can be used to study some of the dissociation-excited transfer reactions or excitation transfer reactions. This type of reaction is in addition to the laser
