Abstract
Protonated cinchona alkaloids and
their dimers undergo photochemical
reaction in the gas phase, leading to UV-specific photofragments,
not observed by collision-induced dissociation. Simultaneous coupling
of UV and IR lasers with a Paul ion trap has been achieved for obtaining
the vibrational spectrum of the fragments arising from the photodissociation.
The structure of the photoproduced radical has been fully characterized
by comparing the experimental spectrum to that simulated by DFT calculations
