Abstract

A summary description of the equipment for time‐of‐flight (TOF) mass spectroscopy and its uses in the x‐ray region for the study of radiation damage (photofragmentation) of biologically relevant molecules is given. The technique is illustrated with some recent x‐ray (∼8.1 keV) TOF results obtained from free adenosine triphosphate and guanine molecules. The well defined time structure of synchrotron radiation has been employed in order to record the molecular decomposition in real time. It has, thereby, been possible to determine which bonds are most susceptible to bond breakage following irradiation of the molecules by x rays.
