✦ Synopsis

Quantum yields for the products from trimethylgalhum (TMG) photolysis were determined via a new method involving isotopic analysis using TMG-acetone-d6

mixtures. The following model-dependent quantum yields were obtained: monomethylgalbum (MMG), 0.5; dimethylgallium (DMG), 0.2; gallium, 0.3; molecularly eliminated ethane, 0.3; free methyl, 1.5. Two new electronic absorptions at 216 and 220 nm were found and are tentatively ascribed to DMG*.

## Abstract The primary quantum yield of H‐atom production in the pulsed‐laser photolysis of hydrazine vapor, N~2~H~4~ + hν → H + N~2~H~3~, was measured to be (1.01 ± 0.12) at 193 nm relative to HBr photolysis, and (1.06 ± 0.16) at 222 nm relative to 248‐nm N~2~H~4~ photolysis, in excess He buffer
