The result show that the UV-Vis absorption spectra at 460 nm of beta-carotene disappeare in polar solvent 1,2-dichloroethane. And a new, intense absorption band of complex which was formed by beta-carotene and iodine was found at 1000 nm. So the resonance Raman spectra of beta-carotene in complex couldn't be observed by 514.5 nm Laser. And Raman cross section of beta-carotene that wasn't in the complex reduced. Due to the solution of beta-carotene and iodine was unstable, the molecule structural order of beta-carotene weaked, which lead to the weak of coherent weakly damped C-C vibrations, and made the Raman scattering cross section reduced.

2摘要:experimental setups, both established in the Kiefer group, are treated. In a transient four-wave-mixing (FWM) experiment, where two pulses interact simultaneously with the system, the interaction with a third time-delayed pulse leads to light emission reflecting ground state vibrational dynamics in I-2. On the other hand, delaying a FWM-pulse sequence with respect to a single pump pulse interacting with beta-carotene yields a signal that is directly proportional to the population of a selected nuclear eigenstate in the electronic ground state. Thus, within this setup, it is possible to monitor ground-state re-population dynamics mode specifically. Copyright (C) 2006 John Wiley & Sons, Ltd.
