摘　　要：结晶紫和结晶紫母体在强有机酸中,其甲基峰都移向低场。在取代的芳烃溶剂中,甲基峰都移向高场,而且彼此间的化学位移有线性关系,并与Hammett取代基常数及改正的Hammett取代基常数间有线性关系。讨论了电子移动度的应用以及取代基常数σ与σ^-间的线性关系。In this paper, the results of the solvent effect of crystal violet and leuco crystal violet by ~1H NMR are reported. In strong organic acids, all the methyl peaks shift to downficld. In the substituted benzene solvents, all the methyl peaks shift to upfield. There arc linear relationships between the methyl chemical shifts of CV and LCV and the Hammett and the modified Hammett substituent constant. The use of electronic mobility and the linear relationship between the substituent constant a and a^- are discussed.
