Buchanan, Gerald W. published the artcileCarbon-13 nuclear magnetic resonance studies of ortho-substituted anisoles and diphenyl ethers, Quality Control of 2944-47-0, the publication is Canadian Journal of Chemistry (1974), 52(5), 767-74, database is CAplus.
Carbon-13 NMR chem. shifts for 8 anisoles and 15 diphenyl ethers are reported. para-Carbon shieldings are sensitive to the degree of steric interference to conjugative electron release by the ethereal O atom. An empirical correlation between the para-carbon shifts and the average twist angle of the Ph rings from a reference plane was developed. Satisfactory agreement was found between the angles of twist derived from C-13 chem. shifts and those based on other phys. measurements.
