Steric Effects Vs. Electronic Effects
The structure, properties, and reactivity of a molecule is dependent on straight forward bonding interactions including covalent bonds, ionic bonds, hydrogen bonds and lesser forms of bonding. This bonding supplies a basic molecular skeleton that is modified by repulsive forces. These repulsive forces include the steric interactions described above. Basic bonding and steric are at times insufficient to explain many structures, properties, and reactivity. Thus steric effects are often contrasted and complemented by electronic effects implying the influence of effects such as induction, conjunction, orbital symmetry, electrostatic interactions, and spin state. There are more esoteric electronic effects but these are among the most important when considering structure and chemical reactivity.
A special computational procedure was developed to separate electronic and steric effects of an arbitrary group in the molecule and to reveal their influence on structure and reactivity.

Famous quotes containing the words effects and/or electronic:
“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
“The car as we know it is on the way out. To a large extent, I deplore its passing, for as a basically old- fashioned machine, it enshrines a basically old-fashioned idea: freedom. In terms of pollution, noise and human life, the price of that freedom may be high, but perhaps the car, by the very muddle and confusion it causes, may be holding back the remorseless spread of the regimented, electronic society.”
—J.G. (James Graham)
