Abstract
Laser-induced multiphoton ionization of molecules in the gaseous phase has been the subject of many experimental and theoretical investigations recently. However, little attention has been given to similar processes in the liquid phase. We report and dis- cuss results obtained with a conductivity technique1,2 on (1) the photoionization of N,N,N',N'-tetra- methyl-p-phenylenediamine (TMPD) in liquid hydrocarbons, (2) autoionizing states of fluoranthene in liquid n-pentane, and (3) the effect of coherent vs resonant (stepwise) two-photon excitation In the photoionization process in solutions.
