A new spectroscopic method for monitoring Doppler-free two-photon absorption signals is analyzed. Its principle consists of high-frequency modulation of one of the incident beams and the detection of the modulation induced by two-photon absorption in the intensity of the counterpropagating beam. The predictable advantages of this ...
High-quality films of copper phthalocyanine (CuPc) prepared in situ were used as a model to characterize unoccupied states of organic molecular semiconductors. We demonstrate that a combination of high-resolution near-edge x-ray absorption together with first-principles calculations constitutes a reliable tool for the detection and identification of ...
The photophysical and photochemical reactions, after light absorption by a photosynthetic pigment-protein complex, are among the fastest events in biology, taking place on timescales ranging from tens of femtoseconds to a few nanoseconds. The advent of ultrafast laser systems that produce pulses with femtosecond duration opened up a new area of research and enabled ...
