REFERENCE DATA causes the electron density to be comparatively lower at C-3 and C-5 than at C-2 and C-4, so that the former signals resonate at lower fields. Distinction between the signals of the C-2/C-4 and C-3/C-5 pairs was achieved by comparing the C-H coupling patterns of 5 and 1. Compounds 1,
## Abstract The ^13^C NMR spectra of 17 methylโ and ethylโsubstituted tetrahydrofurans and 58 alkylโ and arylโ substituted 1,3โdioxolanes are reported. For the cases in which substituents recur, additive substituent parameters are calculated and compared with similar parameters in cyclopentanes and
