摘要
For three series of mono-, di-, and trisubstituted pyridines, respectively, available incremental methods and calculation programs for estimating the corresponding C-13 NMR chemical shifts were employed and compared with the results obtained. The following methods and programs were used for testing them for their accuracy: simple pyridine increments, a simplified increment calculation on the base of benzene increments (program AROSIM(1,2)), the calculation method of Furst and Pretsch(3-6) (Carbon-13 module for ChemWindows), SPECAL from Specinfo(7) (a database founded calculation program), CSPEC2,(8,9) gNMR,(10) CNMR,(11) and HyperNMR,(1,2) respectively.
