When electromagnetic radiation in the ultraviolet (UV) or visible region of the spectrum is absorbed by a molecule, π or non‐bonding (n) electrons are promoted into antibonding orbitals. Because the main electron transitions are π→π* transitions, the absorption of energy in the UV or visib...

ULTRAVIOLET-VISIBLE SPECTRA MEMBRANE OF NAFIONAlmeida, Selma helena deKawano, Yoshio
Ultraviolet-visible spectra of Nafion membranedoi:10.1016/S0014-3057(96)00217-0The effect of pre-treatment, counterion and electrolyte concentration, temperature and aging of Nafion 117 membrane was investigated by electronic absorption spectroscopy. The band at 196 nm is sensitive to the cluster ...
á857ñ ULTRAVIOLET-VISIBLE SPECTROSCOPYINTRODUCTIONUltraviolet-visible (UV-Vis) spectra are derived when the interaction between incident radiation and the electron cloud in achromophore results in an electronic transition involving the promotion of one or more of the outer shell or the bonding elec...
