Multiphoton ionization and excitation of fluoranthene and benzene in solution

Technical Report ·
OSTI ID:6893887
; ;
Multiphoton ionization and excitation spectra of fluoranthene and benzene in dilute solutions of n-pentane have been measured utilizing, respectively, a sensitive multiphoton conductivity and a two-photon excitation technique. The order of the multiphoton ionization process in benzene solutions has been determined, and its significance in the determination of the ionization threshold of benzene in solution is discussed. The potential capability of the multiphoton ionization technique to laser-analytical instrumentation in the liquid phase is indicated.
