Abstract This paper studies the isotopic effect of Cl2+ rovibronic spectra in the A2$\Pi$u ($\varOmega$ = 1/2) - X2$\Pi$g($\varOmega$ = 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 A2$\Pi$u and X2$\Pi$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.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
