摘要
对查尔酮类共轭体系的电子光谱,CNDO/2计算及线性关系文献中已作了全面报道。本文用林惠心等在徐光宪改进的HMO法基础上提出的改进HMO法(即MHMO法),对查尔酮类共轭体系进行了计算,结果λ_计和λ_实基本一致,线性关系良好。
The longest-wave length absorption of conjugated systems of chalcones in electronic spectra have been calculated by the modified HMO(MHMO) method. The linear relations between then calculated wave length of MHMO、HMO、CNDO/2 and the experimental wave length、reduction potential in polarography have been studied.
