Photomodulation spectroscopy

By an extensive study by optical, Raman and photomodulation spectroscopy of samples of polyCPDA and polyDCHD we have been able to recognize that different electronic photoexcitations occur in these polymers. Long-lived metastable bipolaronic states are photogenerated in polyCPDA as inferred from the behaviour of the two PA bands exhibited by this polymer. On the contrary, the PA spectrum of polyDCHD... [Pg.202]

Polarization Modulation in FTIR Spectroscopy (PM-FTIRS). Recently, Kunimatsu, Golden, and coworkers have coupled the polarization modulation technique with Fourier transform infrared spectroscopy and applied the new method to electrochemical studies (Figure 20). In their work, a double modulation technique is employed, using a photomodulator working at high frequency (78 kHz) and a polarizer, both inserted in the optical path. [Pg.223]
