Fluorescence line spectra of etio- and coproporphyrin isomers and mesoporphyrin IX, as well as their ionic forms have been obtained and investigated using a tunable dye laser excitation (T = 4.2 K). Normal vibrational frequencies in the ground electronic state of both the neutral molecules and their ions have been determined. By comparing the line spectra of different porphyrins and their isomers the distinctions have been revealed which may be used for the identification of these compounds in solutions. Changes have been discovered in the coproporphyrin ion spectra in different solvents.
使用可调谐染料激光激发（T = 4.2 K）获得并研究了初卟啉和粪卟啉异构体以及中卟啉IX及其离子形式的荧光线光谱。已确定中性分子及其离子在基态电子态下的正常振动频率。通过比较不同卟啉及其异构体的线光谱，揭示了可用于鉴定溶液中这些化合物的差异。还发现了不同溶剂中粪卟啉离子光谱的变化。
