✦ Synopsis


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.

## Abstract The calculation of some carbon and nitrogen screening constants and chemical shifts is reported. The independent electron theory developed by Pople is used as the basis of the calculations. Within this framework the MINDO/3 parameterization scheme is employed and shown to provide quanti
