Mass-selected projectile ions in the tens of electronvolt energy range undergo surface-induced dissociation upon collision with a liquid perfluorinated polyether (PFPE) surface. The efficiency of translational-to-vibrational (T-V) energy transfer is similar to that observed for a fluorinated self-assembled monolayer (SAM) surface. The thermometer ion W(CO)^' was used to detenrrine an average T-V conversion efficiency of 18% in the collision energy range of 30-50 eV. The surface can be bombarded… CONTINUE READING
