Eigenstate resolved infrared-infrared double-resonance study of intramolecular vibrational relaxation in benzene : first overtone of the CH stretch.
The first eigenstate resolved, near the infrared spectrum of benzene in the region of the first C-H stretch overtone (6000 cm{sup -1}) has been obtained with an IR-IR double-resonance molecular beam optothermal spectrometer. Using a hierarchical tree analysis and level spacing statistics, we show that the intramolecular vibrational relaxation occurs nonergodically over at least seven different time scales ranging from 100 fs to 2 ns.
