✦ Synopsis

Quantum yields for the loss of disilane and the formation of silane in the 193 nm photodissociation of disilane have been measured using time-resolved infrared diode laser absorption spectroscopy under single excimer laser pulse conditions at total pressures of 5 to 10 Torr in helium buffer gas. The total quantum yield for loss of disilane is 0.7 k 0.1 while the quantum yield for formation of silane is only 0.10+0.03.

The results suggest that numerous photodissociation pathways as well as non-photodissociative relaxation pathways exist for disilane excited near its electronic absorption threshold.

Laser photolysis of dicyanoacetylene at 193 nm and at 248 nm, leading to the production of CN, C, and (probably) &N, has been investigated. CN violet bands and Cz Swan bands were observed in absorption. Photolysis at 193 nm produces CN in both the X %+ and in the A 'II, manifolds, the latter -probab

## 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
