Pump-probe laser photolytic fragmentation fluorescence spectrometry of isomeric alkenes
- Univ. of Tennessee, Knoxville, TN (United States)
The two-laser {open_quotes}pump-probe{close_quotes} photolytic fragmentation fluorescence spectometry of three octenes and two nonenes is described. Probe-laser-induced C{sub 2} fluorescence (Deslandres-d`Azambuja system, C{sup 1}II{sub g}{updownarrow}A{sup 1}II{sub 11}) is detected. The relative C{sub 2} fluorescence intensity and spectral patterns exhibited by each alkene are strongly dependent on the probe-laser wavelength. The dependence of the fragment fluorescence intensity on the probe-laser fluence implies that the {open_quotes}probe{close_quotes} laser induces photofragmentation of intermediate species produced by the {open_quotes}photolysis{close_quotes} laser. 23 refs., 5 figs., 3 tabs.
