• Resumen

  • Laser-Induced Optoacoustic Spectroscopy (LIOAS) is used to study the electrón transfer (ET) processes in three different model systems: 1. the triplet state of the Flavio mononucleotide (FMN) and trytophane and tyrosane, 2. a water soluble porphyrine and benzoquinone and 3. Zn-porphyrine and methylviologen unit linked by two different bridges and included in micelles.

    LIOAS affords time-resolved thermodynamic profiles from few nanoseconds to microseconds alter photoexcitation as well as the volume changes associated to those processes. Together with other techniques, transient absorption and fluorescente, large information on the ET processes is obtained.
