摘要
This paper studies the isotopic effect of Cl2^＋ rovibronic spectra in the A^2Лu （Ω = 1/2）-X^2Лg （Ω = 1/2） system. Based on the experimental results of the molecular constants of ^35Cl2^＋, it calculates the vibrational isotope shifts of the （2, 7） and （3, 7） band between the isotopic species ^35C12^＋, ^35Cl^37Cl ＋ and ^37Cl2^＋, and estimates the rotational constants of both A^2Лu and X^2Лg states for the minor isotopic species ^35Cl^37Cl＋ and ^37Cl2^＋. The experimental results of the spectrum of 35Cl37Cl-1- （3, 7） band proves the above mentioned theoretical calculation. The molecular constants and thus resultant rovibronic spectrum for ^37Cl2^＋ were predicted, which will be helpful for further experimental investigation.
