EFFECT OF THE SUBSTITUENT ON THE POTENTIAL-ENERGY SURFACES AND VIBRATIONAL-MODE STRUCTURE IN THE MONOSUBSTITUTED BENZENE ARGON VANDERWAALS COMPLEXES

For the first time, the effects of substitution on the potential energy surface and external vibration mode structure are investigated in a variety of monosubstituted benzene-argon van der Waals complexes, using the atomic interaction sum model. The perturbations induced, due to substitution, are explicitly discussed relatively to the benzene-argon complex and the results are compared with the recent experimental data. © 1990.
