摘　　要：对十个化合物的紫外吸收性能进行了测定。对其紫外吸收构效关系进行了探索,用振子强度f_n的概念来反映化合物的紫外吸收强度。结果表明f_n与PPP量子化学参数SOSC修之间存在着定量关系。在考虑到溶剂和不同取代基的影响后,发现紫外吸收频率和PPP量子化学参数——前线轨道能量差△E_(?),之间也有良好的线性关系。The UV spectra of ten compounds were measured and their QSAR to the UV absorption were studied. The relationship between f_n, which denotes the oscillator strength, and SOSC was obtained. With the influence of solvent and substituents, having been considered a good linear relationship between v and △E_n is also obtained.
