Spectral dependences of the absolute quantum yields of I( 2P1/2) atoms in photolysis of C2H5I and C3H7I by λ = 240–290 nm radiation

Measurements were made of the absolute quantum yields of I( ²P_1/2) atoms, Φ_I* (λ), in the photolysis of C₂H₅I and C₃H₇I in the λ = 240–290 nm spectral range. It was established that nonadiabatic processes influence the values Φ_I* (λ).
