Title: | Retarded intermolecular interactions involving diamagnetic molecules | Authors: | SALAM, Akbar | Issue Date: | 2000 | Publisher: | JOHN WILEY & SONS INC | Source: | INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY, 78(6). p. 437-442 | Abstract: | Second- and third-order time-dependent perturbation theory within the multipolar framework of nonrelativistic quantum electrodynamics is used to calculate the retarded dispersion interaction between two diamagnetic molecules, a diamagnetic molecule and a magnetic-dipole susceptible molecule, and a diamagnetic molecule and an electric-quadrupole polarizable molecule. New expressions for the energy shift valid for all intermolecular separation distances, R, beyond the region of overlap of molecular electronic wave functions and applicable to a pair of randomly oriented molecules in the ground electronic state are given. The R-dependent behavior of the far-zone limit of the interaction energies is also examined.
