摘要: 利用激光光谱技术得到NO分子在420~470 nm的荧光激发谱及A2∑←X2∏(0,0)跃迁的荧光时间分辨谱.荧光激发谱归属于A2∑←X2∏(0,0)(0,1)跃迁.根据实验测得的数据,得到A2∑(v=0)态得力常数k=2.32×103 N/m,自然寿命τ0≈195 ns.

Abstract: Two photons fluorescence excitation spectrum in the range of 420~472 nm of NO is obtained.The spectrum is attributed to A2∑(v′=0.1)←X2∏(v″=0)Transition.The value for force constant of k=2.32×103 N/m is gotten.The fluorescence decay spectrum of A2∑(v′=0)→X2∏(v″=0,1…)at different pressure are measured.The value for the spontaneous radiative lifetime of A2∑(v=0) is 195 ns.

Key words: NO, Fluorescence excitation spectrum, Fluorescence decay spectrum
