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