本文运用光声光谱方法研究了第一过渡系列金属酞菁配合物。在375nm附近发现了一个新的吸收峰,指认亥峰为金属原子dπ轨道电子向酞菁环eg(n~*)轨道跃迁的荷移带。计论了该吸收带产生的原因及影响因素。
In this paper, the first transition series metal phthalocyanine complexes were studied by photoacoustic spectroscopy. A new absorption peak was found near 375 nm, indicating that the peak is the charge transfer band of the metal atom dπ orbital to the eg (n ~ *) orbit transition of the phthalocyanine ring. The reason and influencing factors of the absorption zone are discussed.
