An anisole+%hanol solution was introduced into vacuum as a continuous liquid flow (liquid beam), and the molecules in the liquid beam were. ionized by laser two-photon ionization. Ions ejected from the liquid beam were extracted by applying a pulsed electric field for the measurement of time-of-flig

A simple technique for making a continuous liquid flow in a vacuum (liquid beam) was developed and combined with multiphoton ionization and time-of4ight mass spectrometry. This technique was applied to the texmanc-e two-photon ionization of aniline in ethanol (0.2-3 M). Binary cluster ions of anilin
