Abstract

IN recent papers dealing with theoretical molecular properties derivable on the basis of quantum mechanics, Coulson and others1,2 stated that the free valence number calculated for a given carbon atom should be related to its ability to interact with a free radical, being a measure for the unused bonding power of that atom.
