In the above paper, we suggested that the observed asymmetric Z-V curves obtained with an STM on Au surfaces coated with hemiquinone monolayers represent molecular switching and rectification. Further studies have shown that films lacking these molecules sometimes exhibit Z-V curves with large disco

β¦ Synopsis
Ab initio calculations on twenty van der Waals dimers of small polar molecules at the experimentally observed intermolecular separation R, using Hartree-Fock molecular moments, show that the minima in the electroslatic mteraction expanded up to R-" converges to angular structures which are close to those observed experimentally for such complexes.

The Morse potential Function for non-polar molecules as suggested by Hirschfelder et al. has been utilized to study analytically the vibration-rotation spectrum of van der Waak moIecuIes like the Nes molecule. The resulting vibration-rotation patterns exhibit some interesa and regular features.
Molecular volumes for hydrocarbons, amino acids, peptides, and 14 globular proteins were calculated by techniques using van der Waals radii and by semiempirical molecular orbital methods. The resulting values were compared to experimentally determined volumes. The values obtained by methods employin
