Photochemistry of radicals and biradicals
Article Abstract:
The luminescence, intramolecular activity and transient absorption of radicals and biradicals in seqential two-photon absorption at room temperature are discussed. Cleavage reactions are found to be engaged in intramolecular activities, which is not observable under low light-intensities. Reactivity with oxygen increased in intermolecular activities and reaction rates of potential hydrogen atoms such as dienes improved.

The photochemistry and photophysics of triphenylmethane dyes in solid and liquid media
Article Abstract:
The published works on photochemical and photophysical aspects of triphenylmethane dyes in solid and liquid medium before Sep 1991 are presented. The absorbance spectra, photophysical deactivation and photochemical reactions of triphenylmethane in addition to causes of dye fading such as temperature, humidity, dye concentration, nature of substrate, gaseous reactants and light spectra, are also discussed.
