This proposal involves the study of the state resolved kinetics of the vibrational relaxation of O2 and NO. The PI postulates that the breakdown of the local thermodynamic equilibrium assumption in regard to the vibrational distributions of O2 and NO in the stratosphere necessitates state specific laboratory studies in order to fully understand ozone formation and destruction. The P.I. will clarify the importance of Slanger's ozone formation mechanism via quantitative measurements of the relaxation of vibrational states in O2 using a tunable Argon fluoride laser to access high vibrational levels. Noting the importance of NO as a stratospheric catalyst of ozone destruction, the PI will also investigate the initial vibrational excitation of NO resulting from reaction of NO2 with O(3P) and to perform state-to-state studies of vibrational relaxation at high total energies.

这一提议涉及到O2和NO的振动弛豫的状态分解动力学的研究。PI假定，为了充分了解臭氧的形成和破坏，必须对平流层中O2和NO的振动分布进行特定状态的实验室研究，以打破局部热力学平衡假设。P.I.将澄清Slanger臭氧形成机制的重要性，通过使用可调谐的氟化氩激光对O2中振动状态的松弛进行定量测量，以达到高振动水平。注意到NO作为臭氧破坏平流层催化剂的重要性，PI还将研究NO2与O（3P）反应引起的NO的初始振动激发，并进行高总能量下振动弛豫的状态对状态研究。
