Molar volumes and ion pairing of lithium halides in alcohols
The concentration dependence of the apparent molar volumes of lithium halides (and electrolytes in general) in alcohols (and solvents permitting association in general) is, in the first instance, due to change...

Solubilization of paraffin gases in aqueous solutions of sodium octanoate
The solubilities of methane, ethane, propane and n-butane were measured in aqueous solutions of sodium octanoate of molar concentrations between 0–0.8M. From these measurements we have computed the standard fr...

Heteronuclear diatomic transition-metal cluster ions in the gas phase: Reactivity and thermochemistry of AgFe+
The gas-phase chemistry of AgFe+ was studied by using Fourier transform ion cyclotron resonance mass spectrometry. AgFe+ is unreactive with alkanes but reacts with cyclic and linear (C4–C8) alkenes. The primary r...

Nonrigid large van der Waals molecules
We address the breakdown of the (nearly) rigid molecule description of molecular structure and spectra, which is realized when the amplitude of atomic motion becomes comparable with the average bond length. Th...
