Abstract:
Vibrational fluorescence induced by IR multiple-photon excitation of hexafluorocyclobutene was measured as a function of laser frequencies. The width and shift of the inhomogeneous broadened fluorescence bands represent the excitation energy. The contrasting shapes of the excitation and previously measured chemical yield spectra are explained by the Poisson distribution of the molecules in the quasicontinuum.
