Dispersed fluorescence obtained while pumping the 6a transition of T-Ar. The spectrometer resolution is 2 cm fwhm. The intensities beyond 55 cm have been enlarged by a factor of 10.

Dispersed fluorescence of ultracold anthracene in a supersonic beam for several values of the excess vibrational energy, which is indicated , but fails at higher energies owing to the onset of IVR processes.

Dispersed fluorescence resulting from excitation of jet-cooled anthracene to S, 1792 cm 1. The upper portion was taken with R 0.5 A. For the lower portion R 1.6 A for the main spectrum and R 3.2 A for the inset. Various bands in the spectra are labeled with their wavenumber shifts from the excitation energy.

Dispersed fluorescence spectra obtained from the origins of the four A-D systems of guanine shown in

Dispersed fluorescence spectra of ABN .

Dispersed fluorescence spectra of free BA, 1

Dispersed fluorescence spectra of jet-cooled indan.

Dispersed fluorescence spectra of jet-cooled r-stilbene for excitation to S, 1246cm-1 . Insets are the blue portions of each spectrum. In all spectra the positions of the excitation wavelength and the 205 cm-1 band are marked. Both the main spectra were obtained with R 0.64 A. For the insets R 3.2 A.

Dispersed fluorescence spectra of jet-cooled t-stilbene for excitation energies that have been observed to give rise to beat-modulated fluorescence decays. Excess energies in S, for the excitations are given in cm-1 in the figure and the excitation wavelengths are marked with arrows in the spectra. The asterisks refer to detection wavelengths for the decays of

Dispersed fluorescence spectra resulting from excitation of jet-cooled anthracene to S, 1420 cm 1. The upper portion was taken with R 0.6 k and the lower with R 1.6 A. Various bands in the spectra are marked with their shifts in cm 1 from the excitation energy.

Dispersed fluorescence spectrum and fluorescence decay resulting from excitation of jet-cooled anthracene to S, 766 cm 1 . An arrow marks the excitation wavelength. The decay corresponds to detection of the vj 390 cm 1 band in the spectrum with R — 3.2 A.

Dispersed fluorescence spectrum from OH A products following vibrational predissociation of OH-Ar complexes with one quantum of OH vibrational excitation.

Dispersed Fluorescence Spectrum of AgAu. The AgAu A — X1 E DF spectrum contains long v — v vibrational progressions because the bond length in the A-state is much longer than in the X-state. The nodal structures of the v 0, 2, and 3 vibrational states are displayed as intensity minima in the DF spectra. Since the vibrational quantum number is equal to the number of internal nodes in the wavefunction, a vibrational progression in an absorption or DF spectrum often reveals the absolute assignment of the initial vibrational state .

Dispersed fluorescence spectrum of formaldehyde CH2O following laser excitation of its X —A 4-5K transition. Information on the energy-level structure and transition probabilities can be extracted from the line positions and the line intensities. Experimental data adapted from Klein-Duwel et al Appl. Opt., 2000, 39
