K. Strasburger, APPROXIMATE REPRESENTATION OF THE MOLECULAR ELECTRON-DENSITY - AN APPLICATION TO THE WATER DIMER AND SOLVATED POSITRON, Computers & chemistry, 22(1), 1998, pp. 7-12
A method for construction; of an approximate representation of the mol
ecular electron density based on the multicentre multipole expansion a
nd conserving the local multipole moments is proposed. It has been use
d for description of the electrostatic component of the interaction en
ergy in the water dimer and for the positron trapped among three, four
, six and eight hydrogen fluoride molecules. Results have been compare
d with ab initio calculations. (C) 1998 Elsevier Science Ltd. All righ
