Abstract
Short polyyne chains (โฉฝC~8~H~2~) were produced by laser ablation of graphite rods in water. The results are compared with those obtained by ablation in acetonitrile using vibrational and UV absorption spectroscopy. Since silver surfaces are able to stabilize the obtained spโhybridized molecules, surfaceโenhanced Raman spectra were recorded and are discussed in terms of surfaceโmolecule interactions. The degradation of the produced species are also considered to support the conclusions. Copyright ยฉ 2008 John Wiley & Sons, Ltd.

A continuous liquid flow of an aniline-ethanol (AN-EtOH) solution was introduced into a vacuum. The liquid beam was irradiated by a focused UV laser in the range 265-300 nm, and product ions ejected into th'e vacuum were analyzed by a reflectron time-of-flight mass spectrometer.

Laser-induced liquid beam ionization/desorption (LILBID) mass spectrometry is capable of desorbing ions directly from a liquid beam into the gas phase by means of an IR laser pulse tuned to an absorption band of the solvent used. Up to now, it has been restricted to the use of alcoholic solutions ow
