Low temperature photolysis of non equilibrium homogeneous mixture of bromine and ethylene, formed by vapour deposition

The regimen of preparing of samples of optical quality formed by vapour deposition at temperature 40 K of separate Br2 and C2H4 to homogeneous mixture as 1 : 4 was determined. Laser photolysis with λ = 441 nm of various zones of the sample at fixed temperatures from 24 K to 75 K under conditions: heating - cooling - second heating were realized. At T = 35 K dark reaction was investigated. The displaying of D-A interactions betwin Br2 and C2H4CH molecules into non equilibrium network of the sample and its influence on quantum outlet of Br2, and activation energy of photolysis of zones with various heating story was discussed.
