Abraham Model Correlations for Triethylene Glycol Solvent Derived from Infinite Dilution Activity Coefficient, Partition Coefficient and Solubility Data Measured at 298.15 K
This article describes the use of a gas chromatographic headspace analysis method to experimentally determine gas-to-liquid partition coefficients and infinite dilution activity coefficients for 29 liquid organic solutes dissolved in triethylene glycol at 298.15 K.

Correlation consistent basis sets designed for density functional theory: Second-row (Al-Ar)
Article presenting cc-pV(n+d)Z correlation consistent basis sets of double- through quintuple-ΞΆ quality for the atoms Al-Ar that have been modified for use with density functional theory (DFT). These basis set modifications include truncation of high-angular momentum basis functions, recontraction of the s- and p-functions, and reoptimization of basis function exponents with generalized gradient approximation and hybrid-DFT functionals. The effects of basis set truncation, recontraction, and reoptimization are shown to improve convergence behavior in atomic energies as well as dissociation energies and enthalpies of formation.
