Abstract
(a). We have computed an approximate absorption spectrum for unstable intermediates
H3≠ which constitute the transition states in the fundamental exchange reaction H+H2→H3≠→H2+H. Reaction takes place across the Siegbahn, Liu, Truhlar, Horowitz
(SLTH) ground state energy surface, and electronic excitation is to the bound state
that correlates with H*(22P)+H2. Features in the spectrum are indicative of the
favored turning points for the mean of many classical trajectories across the SLTH
surface. (b). Preliminary experimental data are reported which give evidence of emission
arising from the transition states of NaI≠* in the (cw or pulsed) photolysis of
NaI→222nmNaI≠*→Na*(32P)+I.
The observed transition state emission is compared with a simple calculation.
