## Abstract Heats of formation calculated by MINDO/3 are reported for 42 carbocations for which experimental heats of formation have been published. Errors associated with these calculations can be large, with an overall range of Β±13 kcal/mol. Correction of systematic errors in the MINDO/3 calculat
First-order hyperpolarizabilities fl of some organic molecules are calculated by the CNDO/S-CI method, with an account taken of intermolecular interactions. The molecular hyperpolarizability is shown to deviate by more than one order of magnitude because of these interactions. The results, obtained
The minimum energy paths for the isomerization of singlet ethylcarbene to propylene and cyclopropane have been calculated by MINDO/Z. The formation of the olefin presents no energy barrier but a critical energy of 1.4 kcal mol-' was found in the path to cyclopropane formation.
