In order to carry out experiments of this type, we have incorporated a tunable IR laser into our experiment that excites the cryogenically cooled anions prior to photodetachment. This new experimental configuration, IR cryo-SEVI, has been carried out on a diatomic anion, OHˉ, and, more recently, on the polyatomic vinoxide anion CH2CHOˉ. The OHˉ anion served as a first demonstration of the technique; it is a special case in the sense that the cryo-SEVI spectrum is fully rotationally resolved and the gas phase infrared spectrum is well characterized. The vinoxide results illustrate the potential and complexity of IR cryo-SEVI, most notably the observation of effects associated with anharmonic coupling between vibrational modes in the anion and neutral as well as the dependence of these effects on the vibrational frequency of the pre-excited mode.
