Resumen:
Simultaneous application of laser absorption spectroscopy and laser induced fluorescence allowed us to obtain kinetic and spectroscopicproperties of the dye 3-3°-diethyloxacarbocyanine iodide (DOCI). Photophysical and spectroscopic parameters of the photoisomeric speciesof DOCI, such as fluorescence quantum yield, isomerization and back-isomerization quantum yields, were obtained.The method developed provides a complete quantitative description for a single photoisomerization process and an accurate value of thephotoisomeric fluorescence quantum yield, relative to the corresponding value of the normal species. © 1997 Elsevier Science S.A.Keywords: 3,3'-diethyloxacarbocyanine iodide (DOCI); Cyanine dyes; Laser absorption spectroscopy; Laser induced fluorescence; Photoisomerization
