Abstract

Production of S₂ (a ¹Δ, v=2) has been observed in the UV photolysis of several reduced sulfur compounds by monitoring the f ¹Δ-a ¹Δ (2-3) laser excitation spectrum. There appears to be at least three production mechanisms including reaction of S (¹D) with the precursor. The f-a (2-3) band shows several spectral overlaps with the OH A ²Σ-X ²Π (1-0) band including the Q₁1 line. Since a significant fraction of the f-a emission from f ¹Δ (v=2) overlaps the OH A-X (1-1) and (0-0) bands the potential for a significant 'interference' signal exists if the two species are produced simultaneously.
