Ultrafast electron diffraction of ionized toluene molecules generated by a near-infrared strong laser field

ORAL

Abstract

Gas phase ultrafast electron diffraction (UED) has been a powerful method to determine the structure and structural dynamics of neutral molecules with great details, but there have not been studies of ions in the gas phase using UED. We use 90 kilo-electron-volt gas phase UED setup to investigate the ionized molecules of toluene generated by a femtosecond near-infrared laser pulse, and momentum-resolved coincidence time-of-flight ion mass spectrometry to determine the relative yield of possible ionic products. The relative yields of main fragmentation channels are determined by combining the two measurements and comparing the diffraction signal to the theory. The fitting of the diffraction signal from ions to the theory shows that electron scattering computation based on independent atom model is not a good approximation for electron scattering of ionized molecules. The diffraction signal of ions is in good agreement with ab initio computation.
