The (X)over-tilde -(A)over-tilde SEP spectra of jet-cooled thiophosgene

摘要

Over 400 (X) over tilde <- (A) over tilde transitions of SCCl2 have been measured by stimulated emission pumping from 209 to 240 THz above the R state zero point. The state provides access to over 100 previously unassigned (X) over tilde state vibrational levels. The vibrational manifold Of SCCl2 now has been mapped to maximum quanta in all six modes of (15, 4, 5, 18, 2, 2), providing a global view of vibrational dynamics. We report anharmonic constants that fit all currently available assigned vibrational energy levels. The onset of free energy flow has not been reached at E/h = 240 THz for states sampled here, in accordance with (B) over tilde state SEP data and a theoretical analysis. (c) 2006 Elsevier B.V.
