Application of increments additivity allows to attribute closed by value signals in the area of 28 ppm in NMR 13C spectra of 1-pentanol (I) and its esters (II, III) for C2 and C3 atoms during calculations of δС2 and δС3 chemical shifts. In case of pentylformate (IIa) on the basis of calculated data it has been suggested to interchange attributions made by authors [2].
