Phonon modes which are strongly coupled to the lowest optical transition of the quasi-one-dimensional organic crystal of MePTCDI ( N - N ′-dimethylperylene-3,4,9,10-dicarboximide) are directly time-resolved as they appear as coherent wavepackets in

Coherent phonon oscillations in quasi-1D organic crystals of MePTCDI (N-N′-dimethylperylene-3,4,9,10-dicarboximide) are directly time-resolved by femtosecond pump–probe experiments. We observe both oscillations caused by intra-molecular vibration

We consider the exciton states in quasi-one-dimensional organic crystals with strong orbital overlap between neighboring molecules. In such crystals, the energy difference between the lowest Frenkel exciton and the nearest-neighbor charge-transfer ex

Fourier transform spectral interferometry is applied to measure both amplitude and phase of the electric field in different types of semiconductor nanostructures, thus determining the real and imaginary parts of the dielectric function. The importanc

The ultrafast vibronic response of organic dye molecules in solution is studied in pump–probe experiments with 30 fs excitation pulses resonant to S0–Sn transitions. The molecular dynamics is probed either by pulses at the same spectral position

Recent experiments with the shortest available light pulses have shown that wave packet motion is even detectable for molecules in solution and persistent on the timescale of typically 1 ps1, 2. However, in these one color experiments it was generall
