Comments: A vacuum ultraviolet photolysis of C2H5Br at 147 nm was studied over a pressure range of 0.5-50 torr at 298 K. 
The effects of additives He and NO were also investigated.
With increasing pressure the product quantum yields i of C2H4, CH4, and CH2H6 remained constant, while that of C2H2  
decreased from 0.03 to almost 0. The absorption cross section at 147 nm was determined to be 2.89e-17 cm2/molecule.
