網頁2007年6月28日 · The concepts of steric energy, steric potential, and steric charge are introduced within the density functional theory framework. The steric energy, representing a hypothetical state with all electrons packed into the lowest orbital and other effects entirely excluded, is a measure of the intrinsic space occupied by an electronic system. 網頁Steric effects may arise in a number of ways.13 Primary steric effects result from repulsions between valence electrons or non-bonded atoms. Such repulsions can only result from …
