摘要

在脉冲电离放电中激发含有一氧化碳的混合气体时，对振动激发的一氧化碳分子的发光动力学进行了实验测量。利用振动级动力学数值模型分析了实验测量到的振动激发分子的发光信号，并确定了一氧化碳分子在 Т = 300 K 时与水分子碰撞时第一振动级的弛豫速率常数。

Determining by Luminescence Dynamics the Relaxation Rate Constant of CO Molecule’s First Vibrational Level on Water Vapor in the Afterglow of a Pulsed E-Beam Sustained Discharge

The luminescence dynamics of vibrationally excited CO molecules upon excitation of a gas mixture containing carbon monoxide in a pulsed electroionization discharge has been experimentally measured. A numerical model of vibrational level kinetics was used to analyze the experimentally measured luminescence signals of vibrationally excited molecules and to determine the relaxation rate constant of the first vibrational level of CO molecules during their collisions with water molecules at Т = 300 K.
