WebJan 1, 2015 · Synonyms Isotope-selective photolysis; Self-shielding Definition The self-shielding effect is a phenomenon expected to occur in a gas medium illuminated by a light source, when a molecule in the gas absorbs light with a particular wavelength that may result in its dissociation. WebIn the conventional resonance self-shielding method, the ultrafine group (UFG) method is a relatively simple and rigorous method. The basic idea of UFG method is to solve the slowing-down equation in an extremely fine-group structure to obtain the UFG spectrum of …
