A new four-dimensional potential energy surface of the Ar-CS2 complex: Dependence on the symmetric and antisymmetric stretching vibrations of CS2

- A new ab initio PES involving the Q1 and Q3 normal modes of CS2 is constructed.
- Each potential has a T-shaped global minimum and two equivalent local minima.
- The shift of the Ar-CS2 complex in the ν1 + ν3 region is first reported.
