芳族羰基化合物如10-甲基吖啶酮形成包括顺磁性和氧化还原活性刘易斯酸的刘易斯酸络合物。刘易斯酸络合物的荧光能量与O2·-−刘易斯酸络合物的荧光能量有很好的相关性，该络合物是由超氧阴离子−刘易斯酸络合物的ESR谱的gz值得到的，因此提供了刘易斯酸酸度的定量测量。
Aromatic carbonyl compounds such as 10-methylacridone form the Lewis acid complexes including paramagnetic and redox active Lewis acids. The fluorescence energies of the Lewis acid complexes are well correlated with the O2•-−Lewis acid complexes derived from thegzz-values of the ESR spectra of the superoxide anion−Lewis acid complexes, thus providing a quantitative measure of the Lewis acidity.
