摘要
The products of a CS-hydrocarbon discharge are elucidated through a combination of mass spectrometry and laser spectroscopy. Sulfur containing species are identified and their structures proposed using spectroscopic considerations. The resonant 2-color 2-photon ionization A(2) Pi <-- X(2)Pi spectrum of HC6S is presented, confirming previous non-mass selective identification. The origin band of the A(2) Pi <--X-2 Pi transitions of HCSS and HC10S were measured at 14838.4(l) and 13333.7(5) cm(-1) by cavity ringdown spectroscopy. The near linear relationship of absorption wavelength and chain length characterizes these species as molecular nanowires exhibiting cumulenic bonding. From these data HC12S is estimated to absorb at 820 +/- 5 nm. (C) 2004 Elsevier B.V. All rights reserved.
