by transferring its vibrational energy to other molecules
typically to solvent through collisions. This ra
transition does not emifllight but has the eifect of heating up
the surrounding medium and bri.nging the dye molecule to its
lowest vibrational level in S1. At this point, the dye molecule
may emit a photon of light and relax to any one of several
vibrational levels in S0 (Figure 2, CL: chemiluminescence).
Alternatively, through a process called internal conversion, the
dye could enter a very high-energy vibrational level of S0 that is
at essentially the same §nergy as the ground vibrational level of
S1 (Figure 2, IC: internal conversion). In this case, the dye
molecule will release the excess vibrational energy through
vibrational relaxation, increasing the temperature of the
surroundings in the process.
The chemiluminescence quantum yield,8’9 ¢cL, of the
lightstick reaction is the number of photons of light (Nphmn)
emitted for every molecule of reactant (Nmctmt) consumed:
