Abstract [en]

The photo-induced dissociation of the trihalide anions I3 - and I2Br- in methanol and acetonitrile solution is investigated using magic angle and polarization sensitive femtosecond transient absorption spectroscopy. The dissociation of I 2Br- and I3 - in acetonitrile are found to be very similar, except at the earliest times. A noticeable solvent dependence for the dissociation process is seen, e.g. in the degree of vibrational coherence and the rotational temperature of the I2 - fragment and in the amount of recombination.
