ABSTRACT. The first-order intermolecular perturbation theory developed in the frame of diatomics-in-molecule approach is used to calculate the potential energy surfaces of the Ar...Cl2 complex in the states which correlate with the X0g+ and B0u+ states of Cl2 fragment. Accurate vibrational calculations performed directly with these surfaces reveal close agreement with available spectroscopic data.
