A technique called tunable atomic line molecular spectroscopy (TALMS) was utilized to detect S/sub 2/ by absorption of a Cr(I) atomic emission line at 3018 A. The Cr line was split into Zeeman components, and a differential absorption measurement was obtained as a function of magnetic field strength. Several closely spaced lines belonging to different branches which result from the triplet splitting in the (7,2) band of the B/sup 3/..sigma../sub u//sup -/-X/sup 3/..sigma../sub g//sup -/ system of S/sub 2/ were resolved. A resolution greater than 6 x 10/sup 4/ was demonstrated.
