Abstract
Recent experiments on gaseous iodine and beta-carotene are analyzed within a wave-packet description of femtosecond-time resolved four-wave mixing spectroscopy. Employing the same formalism, two different 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 I2. 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.
