   Author : Benjamin Bolling; [2017]
   Keywords : Physics and Astronomy;

   Abstract : By using the site-selectivity enabled by synchrotron radiation, we can choose the ionization site on a molecule. Core-ionization can result in that the molecule dissociates into charged (and uncharged) ions. With mass spectroscopy, the dissociated fragments’ mass-over-charge can be identified in a time-of-flight spectrum. READ MORE
