Resolution of alkane molecular polarizabilities into atomic terms

Mostrar todas las versiones(3)

Two additive schemes for resolving average molecular electric dipole polarizabilities into atomic contributions, based on the acceleration gauge for the electric dipole, are outlined. Extended calculations have been carried out for a few terms of the alkane series to test the reliability of the part...
