当环中心上方1埃和下方1埃点不对称时,NICS(1)磁性芳构指数分为NICS(1)和NICS(-1)指数。这两个指数表征的是两个环面而不是环本身的芳构性。我们提出了新的NICS(1)协指数来完成芳香性分析。
The NICS(1) magnetic aromaticity index is split into NICS(1) and NICS(-1) indices when the points 1 angstrom above and below the ring center are inequivalent by symmetry. The two indices characterize the aromaticity of the two ring faces rather than the ring itself. We propose new NICS(1) co-indices to complete aromaticity analysis.
