Resumo

The experimental setup for obtaining fluorescence excitation spectra of molecules cooled in a supersonic inert gas jet is described. Fluorescence excitation spectra of substituted aldehyde molecules cooled in a supersonic jet are recorded using this setup. The spectra obtained using the setup is concluded to have a better signal-to-noise ratio as compared to the spectra known from publications. Further ways to modify the setup for registration of excitation spectra of sensibilized phosphorescence and phosphorescence of semivolatile molecules of polyaromatic hydrocarbons are considered.
