Bending distortions, excited-state

The major discernible difference in the two band systems is the length of the bending progressions and consequent width of the electronic transition. The thioketene bands span a narrow region of about 8000 cm centered at 500 nm, whereas the ketene spectrum covers some 17000 cm centered at about 370 nm. This large difference probably reflects to some degree the limited pressure-path attainable with thioketene due to its instability, but also suggests more extensive Franck-Condon activity and a more distorted excited state in the ketene case. Such a conclusion is consistent with the ab initio results. [Pg.226]
