High resolution (3+1) REMPI and dissociation of acetone via 3pÃn Rydberg transitions

Measurements of multiphoton ionization and dissociation of acetone are reported in the wavelength range 490.0-510.0 nm at 1 nm intervals.To our knowledge there are no available results of (3+1) REMPI on acetone in this region. The experiments were performed using anNd:YAG-OPO (optical parametric osc...

Sumario:Measurements of multiphoton ionization and dissociation of acetone are reported in the wavelength range 490.0-510.0 nm at 1 nm intervals.To our knowledge there are no available results of (3+1) REMPI on acetone in this region. The experiments were performed using anNd:YAG-OPO (optical parametric oscillator) laser system coupled to a time-of-flight mass spectrometer. The experimental results show twodissociation channels of the acetone ion, leading to the products (CH3CO+) and (CH+3 ), the channel CH3COCH+3 !CH3CO+ + CH3 beingthe most favored. The acetone and acetyl ions are observed in the entire wavelength range investigated. Finally, the three-photon resonancemultiphoton spectrum of the acetone 3pÃn Rydberg transition is also reported.
