intermolecular forcesinteraction energyHe atompolar moleculeHFH 2OThe interaction energy between a He atom and a polar molecule (HF, H 2O) is calculated with a gaussian basis set both in the SCF approximation and with the inclusion of the intersystem correlation energy. The long range behaviour...
In light of the TKE response of pure water, the ion-induced enhancement/weakening of the TKE signals may indicate underlying changes in the strength of the intermolecular water–water hydrogen-bonding interactions, by which the rotational–translational coupling is modified. To examine the soundness o...
