摘要/Abstract

摘要： This paper studies the isotopic effect of Cl₂⁺ rovibronic spectra in the A²П_u (Ω = 1/2) - X²П_g(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 ³⁵Cl₂⁺, ³⁵Cl³⁷Cl⁺ and ³⁷Cl₂⁺, and estimates the rotational constants of both A²П_u and X ²П_g states for the minor isotopic species ³⁵Cl³⁷Cl⁺ and ³⁷Cl₂⁺. The experimental results of the spectrum of ³⁵Cl³⁷Cl⁺ (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.
