Trapped ions of different masses can be separated in space within a quadrupole ion trap, making it possible to perform efficient mass-selective photodissociation on a mixture of ions. This method employs an axial quadrupolar dc pulse (1 μs) to force

The effects on ion motion caused by the application of a resonance AC dipole voltage to the end-cap electrodes of the quadrupole ion trap are described. An excimer laser is used to photodissociate benzoyl ions, and its triggering is phase locked to t

The pulsed CO 2 laser photolysis of triethyl phosphite, P(OC 2 H 5 ) 3 is reported. Unimolecular decomposition produces PO(OC 2 H 5 ) 2 and C 2 H 5 . Sequential photolysis and/or subsequent bimolecular reaction yields the observed end products and ac

We present a partial mechanism for excitation and energy transfer in a Ne/O 2 dc discharge. Atomic and molecular concentrations are monitored via the optogalvanic effect. A resonant Penning ionization process is proposed for the production of O 2 + (
