HPLC-UV analysis of TpTpT irradiated with LEEs (10 eV). TpTpT was irradiated as a thin film at room temperature under UHV. Films were recovered from the irradiation cylinders, lyophilized and dissolved in H2O for analysis. Samples were injected without further treatment (a) and after treatment with alkaline phosphatase (b) similar to Fig. 2.
