energies to permit radiationless transitions leading to excited states 

 of the product (13). However, a reaction mechanism becomes a less 

 probable pathway toward chemiluminescence to the extent that it 

 entails conversion into vibration of any part of the released chemical 

 energy, particularly in condensed phase.
