WitrynaPhotofragment spectroscopy has been applied to the photodissociation of methyl, ethyl, n-propyl and isopropyl iodide at 266.2 nm, both to study the process of unimolecular break-up of electronically excited molecules and to determine the energy distributions of the resulting excited fragments. Witryna1 sty 2024 · The impulsive model gives the translational energy for the direct photodissociation as Et = ( Eavl − Eeq) μN-N / μNO-NO+, where μA-B is the reduced mass of two-body A-B system. The available energy for the photodissociation is calculated as Eavl = hν − D0, where D0 is the binding energy of (NO) 2+.
