Abstract: Twenty-one isomeric compounds from nitration of methyl phenyl-, diphenyl-, and (hydroxy)diphenylacetates and the parent compounds were separated by capillary gas chromatography with apolar stationary phase HP-5 and detected by FID and FTIRD. The measured retention indices and infrared spectral data of C=O and NO2 groups were correlated with molecular structure of analytes. The regularities in GC retention as well as in the FTIR, data of isomeric aromatic nitro compounds were formulated. The obtained results can be useful for GC-FTIR identification of ring positional isomers of nitration products of other methyl arylacetates.
