In regards to Alfonso Garcia-Pineres comments on whether chiral stereoisomers
are considered two molecules or conformations of one, I believe conformations
of one molecule is the better concept. A professor here at Wichita studies
inversion reactions of ammonia computationally. An inversion reaction applied
to a chiral molecule would interconvert the two stereoisomers, although the
inversion barrier may be very high in most cases. For this reason, I consider
stereoisomers to be two conformations of one molecule that are interconvertible
but generally have very high barriers to this inversion reaction.

I hope this confuses the issue a bit more! :-)
