摘要
采用吸收光谱和荧光发射光谱方法研究了-系列饱和环状多官能团胺的氮原子之间的相互作用,测定了一系列胺的光物理性质,即荧光量子效率、荧光寿命、辐射速率常数和自猝灭速率常数。使用MOPAC和AMPAC理论计算,得到胺的振荡强度,并探讨了其与光物理性质的关系。
Absorption and fluorescence emission spectroscopic methods were used to study N - N interactions of the saturated cyclic polyfunctional amines. Photophysical properties （fluorescence quantum efficiencies, fluorescence lifetimes, radiative rate constants and self - quenching rate constants ） of the amines were measured. MOPAC and AMPAC theoretical calculations were performed to obtain the oscillator strengths of the amines and discuss their relationship with the photophysical properties.
