The first high quality potential energy surface for the Kr-HF complex is calculated with the CCSD(T) method and avqz+33221 basis set. A mixed basis sets, aug-cc-pVQZ for the H and F atom, and aug-cc-pVQZ- PP for the Kr atom, with an additional (3s3p2d2f1g) set of midbond functions are used. It is found that there are two minima on the potential. The global minimum is located at R-e = 6.70a(0) and theta(e) = 180 degrees with well depth -252.3537 cm(-1). The shallower minimum is - 106.1783 cm(-1) located at R = 6.65a(0) and theta = 0 degrees. We also calculate the bound states of Kr-HF complex. The theoretical spectroscopic constants agree with experimental counterparts. Crown Copyright (C) 2010 Published by Elsevier B.V. All rights reserved.
