Ultrafast photodissociation of I3 - in solution: Direct observation of coherent product vibrations
Abstract
We report the observation of terahertz oscillations in transient transmission measurements following femtosecond UV photolysis of I-3 in ethanol solutions. Transmission signals at 620 nm and at 880 nm, which are above and below the λmax of the known absorption of I-2 oscillate at precisely opposite phase. This and other results presented indicate that though the oscillations we are observing coherent vibration of the I-2 photofragment.
