Kelly,

First of all, this is a very good idea, and in fact reactions are often
studied while in progress by NMR and other instrumental methods. I
realize you meant to be discussing IR, but NMR is perhaps even more useful
in studying the progress of reactions.

Transition states are very difficult (but not impossible) to study due to
their fleeting lifetimes, however other relatively stable reaction
intermediates can be observed by spectroscopic methods during the process
of converting reactants to products.

Anyway, you've hit upon one of the "high end" uses of spectroscopy.
