The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. For example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires...
Anisotropic potential energy surfaces for Ne·HCl, Kr·HCl and Xe·HCl are obtained by simultaneous least squares fitting to molecular beam spectra and rotational line broadening cross sections. A revised potential surface for Ar·HCl is also presented. The potentials are all very similar in shape...
We were given a gaseous sample of hydrochloric acid. HCl is a compound made out of a hydrogen atom and a chlorine atom. Together, these two form... Learn more about this topic: Intermolecular Forces in Chemistry | Definition, Types & Examples ...

Describe the dominant intermolecular force for the following substance: (a) Fe (b) HCl (c) NaCl Intermolecular Forces of Attraction: Intermolecular forces of attraction are weak forces of attraction between two substances that do not result in the formation of a chemical...
Three types of intermolecular interactions are considered: van der Waals (vdW), donoracceptor and hydrogen bonds. Are vdW forces caused by instantaneous dipoles created by electrons’ orbiting the nuclei (London)—or by accumulation of electron density..

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...

For protein purification, pellets were resuspended in lysis buffer (50 mM Tris-HCl pH 7.5, 150 mM NaCl, 20 mM imidazole, 4 mM BME, 20% glycerol), and bacterial cells were lysed by probe sonication at 5% amplitude, 15 s ON and 10 s OFF for 25 minutes. The cell ...
