Wampler, F. B.

Research progress is reported for the period February, 1981 through April, 1981. A means of detecting H/sub 2/S at the 0.1 ppM level via laser-induced fluorescence is being developed. Because the upper electronic states of H/sub 2/S are repulsive, it is necessary to use a two-laser pump-probe technique. The first laser photodissociates H/sub 2/S into HS and H. Subsequently, a probe dye laser is used to pump the HS ground-state radicals to their A/sup 2/..sigma../sup +/ state from which the radicals then fluoresce. (ACR)
