Steric torsion[edit]

It seems an effect has been left out, and that is known as "steric torsion". If anyone cares to add it, take a peek at page 6 of the following paper. http://staffwww.itn.liu.se/~matfa/polyled2.pdf 213.113.60.147 18:16, 30 September 2007 (UTC)

Examples[edit]

I have very hard to understand when this fenomene occur. Can this be answered by presenting examples of when a reaction is stericly restrained? If someone can think of a way of explaining it better, it would be very much appreciated. —Preceding unsigned comment added by 81.230.2.81 (talk) 18:57, 10 October 2007 (UTC)

Unsuitable Reference[edit]

The following paragraph is not properly verified for the purpose of an encyclopedia. The citation, and thus the method described, seem to be from 2007. If so, the computational procedure has most likely not yet been accepted by the scientific community as standard practice. The entire sentence should be removed (as unnecessary information) or revised (to give a better picture of the current state of computational techniques that try to separate the electronic and steric effects, possibly by citing an appropriate review article instead).

"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."[1]
