title: The direct observation of a psoralen-thymine UVA induced solid-state cycloaddition reaction product by single-crystal x-ray diffractometry.
abstract: Single-crystal x-ray diffraction methods have been used to directly observe and simultaneously determine the molecular structure of the UVA induced cis-syn photocycloaddition product in a partially photolyzed single crystal of a psoralen(pyrone ring side)-DNA(thymine) interaction model compound, 1'-(8-oxypsoralen)-8'(thym-1"yl)3',6'-dioxaoctane.
