Abstract: | Based on the measured UV-, IR-, laser-Raman, and mass spectra, and analyzed with the quantum theory, the reaction pattern of an implanted N + ion with tyrosine molecule (Tyr) was deduced. It was found that a substitute reaction of the slow down N+ with the group =C(5)H- of Tyr's benzene ring had taken place. In addition, a new carbonyl group was measured in the irradiated Tyr sample. Hence, a N-heterocyclic compound was formed. |
