Data by NMR and Representations of Self‐Diffusion Coefficients in Carbon Tetrafluoride and the Determination of Intermolecular Force Constants

, 1971
Self‐diffusion coefficients were measured by the pulsed nuclear magnetic resonance method for pure carbon tetrafluoride for the conditions −30 to 75°C and 20–440 atm.

The Theory of Intermolecular Forces

1996
Abstract There have been many developments in the theory of intermolecular forces over the last twenty years or so that have not so far been collected together in book form. After many years of effort, practical methods have emerged for the accurate calculation of intermolecular interactions by perturbation theory.

Induced dipole moments and intermolecular force fields of rare gas-carbon dioxide complexes studied by Fourier-transform microwave spectroscopy

, 1993
Pure rotational spectra and their Stark effects of X-CO 2 type complexes (X:Ne, Kr, and Xe) have been studied by pulsed-nozzle Fourier-transform microwave spectroscopy.

Intermolecular force, surface roughness, and stability of head-disk interface

, 2005
To achieve 1-Tb∕in.2 magnetic recording areal density, the head/disk spacing, or the flying height (FH) of the slider has to be reduced to 2–3nm and the disk surface roughness and the slider air bearing surface (ABS) roughness need to be well considered ...

Intermolecular force fields of large molecules by the fragmentation reconstruction method (FRM): Application to a nematic liquid crystal

, 2004
A new intermolecular force field for the liquid-crystal-forming molecule 5CB (4-cyano, 4‘n-pentyl biphenyl) has been derived from two-body interaction energies, obtained by the fragmentation reconstruction method (FRM).

Molecular valves actuated by intermolecular forces

Physical Review E, 2005
Phase behavior in nanostructured thin films under a gradient in chemical potential is studied via kinetic Monte Carlo simulation. Switching between saturated, partially saturated, and unsaturated states drives precipitous changes in permeation. This phenomenon could render nanostructured thin films as molecular valves, where adsorbate-adsorbate forces ...

Spherical and Aspherical Intermolecular Force Fields for Sulfur Allotropes

, 1999
Elemental sulfur exists in many crystalline forms, with many of these forms being composed of discrete Sn cyclic molecules. Eleven experimentally determined Sn crystal structures are used to define a new spherical S···S intermolecular force field of the (

Non-Contact Electrostatic Surface Force Imaging of Single Protein Filaments using Intermolecular Force Microscopy

, 2001
An electrostatic force image from a single protein filament was measured and visualized in pure water using Intermolecular Force Microscopy (IFM). Refining atomic force microscopy in combination with very flexible cantilevers and an optical feedback ...

Interatomic and Intermolecular Forces

1978
The equilibrium and non-equilibrium properties of matter reflect the interatomic and intermolecular forces. Elementary considerations of the mere existence of liquids lead us to conclude that molecules attract one another when they are far apart.
