Kennedy, R.S. Sinclair Title: The U.V. spectrum and photolysis of P2I4 and PI3 Journal/Source: J. Inorg. Nucl. Chem., 32, 1125-1133, (1970); http://dx.doi.org/10.1016/0022-1902(70)80106-3 Data: table Energy/Wavelength range: 223 nm; 287 nm; 374 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: solution (cyclohexane) pH: 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.
