摘要: The ionization threshold of fluoranthene and TMPD in n-pentane was determined by laser two-photon (TPI) found to be 4.50 ± 0.05 3.88 eV respectively. For both molecules the TPI spectra show distinct structure due autoionization. spectrum suggests that molecule dissociates via first excited singlet state.
