The electronic and infrared spectra of anthranilic acid in a supersonic jet were measured. The fluorescence excitation spectrum is extremely congested. IR−UV hole-burning measurements indicate that only a single ground-state rotamer contributes to

Laser-induced fluorescence (LIF) studies of seven substituted benzene and naphthalene derivatives seeded in a supersonic jet are reported. Dual fluorescence has been observed in aniline, 4-aminobenzonitrile, 1-aminonaphthalene, and 1-cyano-4-aminonap

The photoisomerization of trans-p-coumaric acid (trans-CA) triggers a photocycle in photoactive yellow protein that ultimately mediates a phototactic response to blue light in certain purple bacteria. We have used fluorescence excitation and disperse

The spectroscopy and intramolecular electronic energy transfer (EET) process for a series of molecules, 9-anthryl−(CH2)n−1-naphthyl, n = 1, 3, and 6 (AnN), was investigated in a supersonic jet. For all bichromophoric molecules, the excitation spe

The dependence of the rate of singlet excitation transfer on the donor−acceptor energy gap was investigated in bichromophoric spiranes with symmetry-forbidden zero-order electronic coupling. The fluorescence measurements were performed in a superso

We studied laser ablation of Trp-Gly under the same experimental conditions used previously to successfully seed this fragile, nonvolatile dipeptide into a molecular beam. A film of Trp-Gly was prepared on a brass plate and laser ablated with 11 ns,

Dual fluorescence has been observed in the emission spectra of benzonitrile and tolunitrile seeded in a supersonic jet. This fluorescence has a sharp component that approximates the mirror image of the absorption spectrum and a broad, red-shifted com
