Comments: The u.v. spectrum and photolysis of PI3 and P2I4 in hexane and cyclohexane have been investigated and the stoichiometry of 
the photolysis reaction obtained. A reaction mechanism for the breakdown is proposed and the quantum yield and kinetic behaviour of the 
solutions explained. The maxima of the UV spectrum are listed.
