Abstract

We report the observation of terahertz oscillations in transient transmission measurements following femtosecond UV photolysis of I^âˆ’ ₃ in ethanol solutions. Transmission signals at 620 nm and at 880 nm, which are above and below the Î»_max of the known absorption of I^âˆ’ ₂ oscillate at precisely opposite phase. This and other results presented indicate that though the oscillations we are observing coherent vibration of the I^âˆ’ ₂ photofragment.
