【摘要】 本文报道了CaOH自由基A-X（100）-（000）跃迁的激光激发荧光光谱研究结果。对约100条转动谱线进行了归属,并用最小二乘方拟合得出A²H_1/2（100）态的 B’=0.337097（10）,D＇=0.377（5）×10^-6,P=一0.04039（2）cm^-1。由这些转动谱线的相对强度还推导出CaOH自由基X²∑态的转动温度T_R=308K。更多还原

【Abstract】 The laser excitation fluorescence spectra of CaOH A-X(100)-(000) transitions were investigated. The assignments were made, and the molecular constants of A2II1/2(100) state were derived by least-squares fitting to be B’=0.337097 (10), D’= 0.877(5)×10-6, and P=-0.04039(2)cm-1. The rotational temperature of CaOH was also derived from the relative intensities of the rotational lines to be TR=308K.更多还原
