摘要
采用微扰理论对CO分子振动薛定谔方程进行了理论求解,得到了非谐振子势下的振动波函数及对应的能级能量.由此计算了CO分子基频吸收与第一、第二泛频吸收的相对强度比,以及各吸收带的灵敏吸收波长位置.计算结果与他人的实验结果符合得很好,检验了理论处理的正确性,也为CO气体的泛频吸收检测提供了理论依据.
The Schrodinger equation of the Carbon Monoxide molecule in vibration state is solved by perturbation theory. The vibration wave function and the corre-sponding energy level in inharmonic oscillator potential are obtained. The paper presents the relative absorption intensity ratio beteen fundamental frequency and the first, second over- frequency and the sensitive absorption wavelength position of respective bands by caulculating. These results are in accord with the others＇ experimental ones. They verify the theory is correct and give the theoretical basis for the over-frequency absorption detection of CO gas.
