Abstract
We investigate the intense-field photodynamics of molecules using 50-fs pulses with intensities of 1012 to 1014 W/cm2 at 800-nm from a Ti:sapphire laser. We use a mass spectrometer that avoids focal intensity averaging. We have investigated the isoelectronic target molecules toluene (C6H5-CH3), aniline (C6H5-NH2), phenol (C6H5-OH), and fluorobenzene (C6H5-F). We discuss a resonance-enhanced multiphoton ionization (REMPI) mechanism that includes the AC Stark shifts of the molecular states. We have also investigated CO2 and CS2. For these molecules, no resonance effects are observed.
