— The initial interactions between high‐energy radiation and a sample of condensed matter are complex. However, soon after the initial phases the excitation energy appears in well‐known forms: ions, free radicals, and molecular excited states. These excited species are the immediate precursors of the stable chemical products. The nature of the chemically significant excited species can be inferred by studying the chemical changes induced in solutes which have been well characterized in photochemical studies. RESUMEN Las interacciones iniciales entre radiaciones de alta energía y una muestra de materia condensada son complejas. Sin embargo, Iuego de la faz inicial la energía de excitatión aparace bajo formas bien conocidas: iones, radicates libres y estados moleculares excitados. Estas especies excitadas son las precursoras inmediatas productos dequímicos estables. La naturaleza de las especies excitadas con significado químico puede ser inferida estudiando cambios químicos inducidos en solutos que han sido bien caracterizados en estudios fotoquimicos.
