What is the strongest intermolecular bond in H_2O, HCl, NaCl, and NH_3? What kind of intermolecular forces act between a hydrogen iodide molecule and a chloroform molecule? What is the strongest intermolecular force present between SO2 molecules? (EN values: S = 2.5; O = 3.5) ...
Identity the dominant type of intermolecular force present in the following liquids: (a) {eq}\displaystyle \rm KBr {/eq} (b) {eq}\displaystyle \rm CH_3CH=O {/eq} (c) {eq}\displaystyle \rm HCl {/eq} (d) {eq}\displaystyle \rm O_2 {/e...
Explain the relation between the intermolecular forces present within a substance and the temperatures associated with changes in its physical stateAs was the case for gaseous substances, the kinetic molecular theory may be used to explain the behavior of solids and liquids. In the following descripti...
The intermolecular part of the potential energy surface for the HCl dimer has been studied with ab initio quantum chemical methods. An intermolecular potential, based on quantum chemical calculations has been constructed. The interaction energy consists of electrostatic, induction, and dispersion terms ca...

Calculations on the vibration–rotation energy levels of the Van der Waals trimers Ar2–HF and Ar2–HCl are carried out, in order to investigate the role of three-body (non-pairwise-additive) forces. The present calculations focus on the lowest Van der Waals vibrational state formed from ...
Symmetry-adapted perturbation theory (SAPT) is a method for computational studies of noncovalent interactions between molecules. This method will be discus
Group theory shows that the effects of assuming centrosymmetry may be significant in the [$\zeta \zeta 0$] or $\Sigma $ direction. Assuming that the replacement of deuterium by hydrogen does not change the intermolecular forces, the frequency distribution of function and the heat capacity of ...
