The linear SiC9 cluster has been detected for the first time in Fourier-transform infrared spectra observed when the products from the laser evaporation of Si/C rods were trapped in Ar at ～10 K. Comparison of 13C isotopic shift measu

Photoionization efficiency (PIE) curves for C3 molecules produced by laser ablation are measured from 11.0 to 13.5 eV with tunable vacuum ultraviolet undulator radiation. A step In the PIE curve versus photon energy, obtained with Na as the car

Carbon clusters, formed by Nd:YAG laser ablation of graphite, have been trapped in solid argon at 12K.Using Fourier transform infrared and UV-visible spectrometers in a crossed beam configuration we have recorded the IR and UV-visible absorption spectra of the same carbon/Ar matrix and followed the growth and decay of bands in both regions as a function of matrix annealing temperature and initial preparation conditions.For the IR bands at 2164 and 1998 cm-1, previously attributed to linear C5 and nearly linear C8 clusters, respectively, good correlations have been found with the 223- and 308-nm bands, respectively.The 2164-cm-1/223-nm correlation represents the first positive assignment for an electronic band due to C5.The similarity of the 223-nm band system with the so-called 217.5-nm interstellar hump has been noted and it is suggested that linear C5 clusters may be responsible for this much-discussed feature.Good correlations were also found for the 2039-cm-1/283-nm, 2039-cm-1/410-nm, and 1695-cm-1/586-nm pairs.The 2039-cm-1/410-nm bands are known to originate from C3, while the species responsible for the 1695-cm-1/586 nm pair is suggested to be a cyclic cluster of six or more carbons.A prominent UV band system at 247.1 nm has been correlated with an IR band at 2004 cm-1 and tentatively assigned to linear C9.
