CCL: Percentage of Excited states species per Mol,

 You'd have to also know the kinetics of reversion to the ground state.  Once you
 have that, it's basically a calculus / diff eq problem.

 Subject: CCL: Percentage of Excited states species per Mol,
 Sent to CCL by: Roger Kevin Robinson [r.robinson---imperial.ac.uk] Dear CCL,
 Say you have a known volume of a species say 1 mole of OH radicals.
 You then apply a constant known amount of energy at the right frequency to
 excite a certain percentage of of the mole of OH radicals to the lowest excited
 state. You also know the amount of energy needed to promote one OH radical to
 that excited state.
 Would it be possible to calculate an approximate percentage of excited radicals
 at any given time ?
 Any help appreciated.
