Population Analysis
... From these data we see that the net electron population on oxygen (atom 1) is 8.007728, while the net on carbon (atom 2) and a H atom is 4.596666 and 0.598509. These numbers correspond to the diagonal elements of the array. The off diagonal elements represent the number of electrons shared between ...
