Off resonant dissociation of NH3 to ground state fragments by pulsed CO2 laser radiation

Abstract The dissociation of NH 3 by pulsed CO 2 laser radiation to produce ground state NH 2 ( 2 B 1 ) fragments has been observed both under essentially collision free conditions and as a function of NH 3 pressure, for laser frequencies out of resonance with ground state NH 3 absorption features. Laser excited fluorescence was used for the detection of NH 2 ( 2 B 1 ).
