Comments: The aqueous photolysis of seven alkyl nitrosamines was studied by irradiation in a solar simulator.
The quantum yield for NDMA was determined to be PHI = 0.41 and PHI = 0.43-0.61 for the other nitrosamines.
Molar absorptivity maxima measured for seven nitrosamines at two absorption bands are listed.
