低能氮离子束注入酪氨酸分子时的质量沉积效应

Mass Deposition Effect of N+ Ion Implantation into Tyrosine Molecule

通过对氨离子注入前后酪氨酸（Ｔｙｒ）样品的紫外光谱、激光喇曼光谱、红外光谱及质谱的测量，配合量子计算结果，分析得知注入氮离子慢化后将与酪氨酸分子中苯环的＝Ｃ５Ｈ─基团发生取代反应，并给出了包括能量沉积作用在内的氮离子沉积产物的结构式。

This paper measured the chang of the ultraviolt spectrums,the infre red spectrums,the Laser-Raman spectrums and the mass spectrums for the tyrosine samples implanted by N+ ion beam. Based on the results of quantitative calculation,it was indicated that the slowed-down implanta-tion N+ ion reacted with the tyrosine molecule and substitute the=C5H─group.Finally,thestructure of the product produced by N+ ion deposition was proposed.
