Laser-induced fluorescence technique to monitor H/sub 2/S (PR 16023). Quarterly technical progress report, May 1, 1981-July 31, 1981

OSTI ID:6344570
The objective of this research project is to develop a means for detecting H/sub 2/S at the 0.1-ppM level via laser-induced fluorescence (LIF). 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 (ArF, 193 nm) photo-dissociates 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. This fluorescence signal can be related back to the H/sub 2/S concentration prior to dissociation and thus affords a real-time diagnostic for the species of interest. Progress is descirbed.
