Abstract
The use of a biased activation cell for performing photodissociation experiments on a triple sector ion-beam mass spectrometer is described. The objective of this work is to eliminate or reduce background signals from metastable ion and/or residual collision-induced dissociation and thereby increase sensitivities for laser-ion beam photodissociation. Selected photodissociation reactions demonstrate the utility of the biased activation cell. Biasing the activation cell separates a significant fraction (⪢ 85%) of the metastable background from the photodissociation signals, thereby increasing signal-to-noise ratios and shortening data collection times in the photodissociation experiment. In addition, the rates of photodissociating ions can be estimated. The photodissociation mass spectra of the geometric isomers trans,trans-2,4-hexadiene and cis,trans-2,4-hexadiene ions (C 6H + 10 are distinguishable.
