Abstract

Preliminary findings are reported following the detailed analysis of intramolecular vibrational energy redistribution (IVR) in S₁ para-fluorotoluene following the excitation of one quantum in the CF stretching mode ν₇. It is shown that the method proposed has the potential to enable not only the determination of a rate constant for IVR, but also the identification of the dark states into which energy has redistributed. In addition energy flow has been observed from a bright state (11¹) previously thought to be below the onset for IVR in this molecule, and evidence of mode-specificity in the IVR process.
