## Abstract The ^13^C FT‐NMR spectra of thirteen furans, monodi‐ or trisubstituted with methyl and/or __t__‐butyl groups, were studied in detail. Substituent effects of methyl and __t__‐butyl groups on the chemical shifts of ring carbon atoms are additive in nonsterically hindered furans. Steric sh
