摘　　要：研究了吡啶、碘络合过程中紫外-可见吸收光谱的变化,并应用液芯光纤技术探测了低浓度吡啶-碘络合物的拉曼光谱。吡啶-碘络合物生成过程中,碘的吸收峰由520 nm蓝移至422 nm,吡啶的各拉曼带均发生微小蓝移。The change of UV-absorption spectra for complexation reaction of pyridine and iodine was studied,and the Raman spectrum of pyridine-I2 complex at low concentration was obtained by liquid core optical fibre.The results show that the absorption peak of iodine shifted from 520 nm to 422 nm,the Raman bands of pyridine are blue-shifted slightly in the process of complexation reaction.
