The S I state of jet-cooled 4-(N,N-dimethylamino)-4'-cyanostilbene (DCS) was studied by picosecond fluorescence spectroscopy. The line structure of the S O -\* Sl-excitation spectrum is a superposition of transitions characteristic of isolated trans-sti~bene and the dimethylamino group. Rotational c

✦ Synopsis
Fluorescence escitation and dispcrscd lluorcscencc spectra of jet-cooled 1 .I'-binaphthyl are reported and sndlysed. The spectra indicate that in the ground Jnd exited state the naphthalene rings are pcrpendiculdr to one another. The spectrs cdn be Iitrthrr interpreted in terms of an ehciton model with an cxciton splittin_r of 21 cm-' . m tile origin. From the structurelcss emission spectrum and lifetime ir. is concluded lhl, in the isolated molecule, efficient vibrational relaation

Resonant two-photon ionization spectroscopy has been used to study the supersonically cooled metal cluster, A&u. One electronic band system has been observed, with the origin band at I7525 cm-'. Vibronic progressions have been found and analyzed using a least-squares fitting procedure. The molecule
The resonanceenhanced ionization spectrum of a trimethylcyclohexene compound in which the cyclohexene ring is formally conjugated to a phenylbutadienyl system has been recorded in a supersonic jet expansion. Two strong origin transitions, associated with different ground-state conformers, were ident
We report the first gas-phase spectroscopic study of iron mononitride (FeN). FeN molecules were generated by the reaction of laser-ablated Fe atoms with NH 3 under supersonic jet-cooled conditions. Laser-induced fluorescence excitation spectra were measured between 16 300 and 21 600 cm Ϫ1 , and rota
Free radicals are produced by excimer laser flash photolysis of a suitable precursor inside the nozzle of a pulsed slit jet and cooled by supersonic expansion from the slit. The infrared spectra of the radicals are then probed by a single-frequency colorcenter laser. This technique has been tested o
