Photodissociation of laser aligned iodobenzene: Towards selective photoexcitation

A study was conducted on the photoexcitation at 266 nm of one dimensionally aligned iodobenzene molecules. As such, the process of how the dissociation rate of iodobenzene molecules can be optimized by polarizing the dissociation laser pulse parallel to the axis of the alignment pulse was shown. This paper demonstrates selective enhancement of the two dissociation channels by polarizing the dissociation pulse either parallel or perpendicular to the alignment pulse polarization and discusses how the use of three dimensionally aligned molecules should improve this selectivity.
