The femtosecond photodissociation of CsI in the CsI–CH3CN complex has been studied. Recurrences are observed in the detection of the Cs+–CH3CN ion complex. They are assigned to the first vibrations of the Cs–NCCH3 bond formed after the CsI dissociation. This result is in good agreement with calculations on the similar NaI–CH3CN system which predict a linear structure for the ground state complex.
