Abstract:
Using differential velocity-modulation spectroscopic technique,the Doppler-limited rotational absorption spectra of the weak band(2,3)in the Comet-tail system(A2Π-X2Σ+) of CO+ were measured.The assignment was made for all the observed spectra.Furthermore the effective molecular constants of the states involved in the transition were obtained,and the constants of the lowerstate v"=3 were reported for first time as to our knowledge.The absorption sensitivity of the experimental sytem was measured to be 1.56×10-6 under the 1slock-in amplifier integration time.

摘要:
利用差分速度调制分子离子激光光谱技术,首次测量了CO+彗尾带系(A2Π-X2Σ+)(2,3)弱带转动吸收光谱,通过对测量谱线的标识,获得了两态的分子常数,其中下态v"=3的常数未见有文献报导。在锁相放大器1s积分时间下,实验系统的吸收测量灵敏度实测为1.56×10-6。
