The Polarity and Solvation option in MolCalc

+Maher Channir, under the capable supervision of MolCalc designer +Jimmy Charnley Kromann, has added a great new feature to the Molecule Calculator, shown in the video below.



Some technical stuff
The solvation energy, molecular surface area, and dipole are computed using the PM3/PCM interface recently implemented in GAMESS by +Casper Steinmann.  The displayed surface, which is slightly different than that used by GAMESS, is computed by JSmol, which also computes the eletrostatic potential based on charges computed by OpenBabel when making a mol2 file.

Computational Chemistry Highlights: July issue

The July issue of Computational Chemistry Highlights is out.

CCH is an overlay journal that identifies the most important papers in computational and theoretical chemistry published in the last 1-2 years. CCH is not affiliated with any publisher: it is a free resource run by scientists for scientists. You can read more about it here.

Table of content for this issue features contributions from CCH editors Steven Bachrach, Ben Corry, Gerald Monard, Dean Tantillo, and Jan Jensen:

Towards First Principles Calculation of Electron Impact Mass Spectra of Molecules

Evaluation of Triplet Aromaticity by the Isomerization Stabilization Energy

Tunneling in the Bergman Cyclization

Enantioselective Thiourea-Catalyzed Intramolecular Cope-Type Hydroamination

Will molecular dynamics simulations of proteins ever reach equilibrium

Atomic-level simulations of current-voltage relationships in single-file ion channels
