The metaiioporphyrins form a diverse class of molecules exhibiting complex and varied photochemistries. Until recently time-resolved absorption and fluorescence spectroscopies were the only methods used to study metailoporphyrln excited state relaxation in a submicrosecond regime. In this paper we present the first picosecond time-resolved resonance Raman spectra of excited state metaiioporphyrins outside of a protein matrix. The inherent molecular specificity of resonance Raman scattering provides for a direct probe of bond strengths, geometries, and ligation states of photoexcited metaiioporphyrins.

A number of different characterization methods have been performed on poly(thiophene) and poly(alkylderivative)s. NMR of electropolymerized poly(thiophene) films has been studied by Hotta et al. and Osterholm et al. An infrared study about vibrational key band on poly(thiophene) films and FT-IR spectra were also published. Resonance Raman scattering on poly(methylthiophene) and x-ray scattering on poly(thiophene) were performed x-ray photoelectron spectroscopy has been reported on FeCls-doped poly(hexylthiophene) and electrochemically obtained poly(thiophene) [20]. Time resolved fluorescence studies on thiophene oligomers are given by Chosrovian et al. [79]. For studies on oligothiophene films see [80,81]. 

Figure 10.15 Resonance Raman detection of populations in electronically excited states and following creation of state molecules by laser excitation at frequency Probing molecules at frequency will generate intense resonance Raman emission at if the - transition is El -allowed, because is in near-resonance with the energy separation between vibration less and some vibronic level of S2. Probing at frequency tu will generate similarly intense emission only if appreciable population has accumulated in by intersystem crossing from S, since a is in resonance with the T — T, energy gap. This excited-state selectivity of resonance Raman scattering has rendered it a useful tool for monitoring time-resolved excited state dynamics.
