我们研究了水溶性的中位一四(4-N甲氧羰甲基吡啶)卟啉及其锌配合物的共振拉曼光谱和表面增强拉曼光谱。对其拉曼特征频率作了经验式的归属,同时还研究了溶液酸度对它的表面增强拉曼光谱的影响,并对其表面增强机理进行了初步探讨。
We investigated the resonance Raman and surface-enhanced Raman spectra of a water-soluble, intermediate-tetra (4-N-methoxycarbonylpicolinopyridine) porphyrin and its zinc complexes. The Raman frequency is assigned empirically. The effect of solution acidity on its surface-enhanced Raman spectra is also studied. The surface-enhanced mechanism is also discussed.
