摘要: We report on picosecond/molecular beam studies of alkylanilines. The reveal important discrepancies between real-time measurements and inferences from spectral broadening data. observe quantum recurrences we find that the observed severe congestion does not correspond to coherence. effect mode symmetry energy IVR dynamics is also examined.
