The potential energy surface for interaction of second excited state of CS2 (1VB2) with Ar by using the equation-of-motion coupled cluster theory

Potential energy surfaces (PESs) are important not only in ground state but also inelectronically excited states in to gain worthwhile spectroscopic information about weaklybound complexes. Some theoretical studies of the PES of Ar-CS2 complex referred to groundstate have been performed [1,2]. Recently, The sixteen lowest PESs of the electronicallyexcited Ar-CS2 complex were calculated in singlet state based on vertical excitation [3]. Inthis work, we evaluate the PES of the Ar-CS2(V1B2) as electronically excited state complexesand investigate the effect of van der Waals interaction on the emission of CS2(V1B2).
