Infrared Multiple Photon Dissociation

We report infrared multiple photon dissociation spectra of cryogenically-cooled (NaSO4−)2(H2O)n dianions (n = 0–6, 8) in the fingerprint spectral region, which provide evidence for a remarkable stability of the quaternary ion complex upon microhydration.

Infrared Multiple Photon Dissociation

The effect of ionization by oxidation and protonation on the structure and IR spectrum of isolated, gas-phase triphenylamine (TPA) has been investigated by infrared multiple photon dissociation (IRMPD) spectroscopy in the fingerprint range from 600 cm−1 to 1800 cm−1 using an infrared free electron laser.
