## Abstract Relative signs of ^13^C๏ฃฟ^13^C coupling constants between ring carbons and carbonyl carbons in dimethyl phthalate and phthalic anhydride, ^13^Cโ€labelled in both carbonyl groups, have been determined. The twoโ€and threeโ€bond coupling constants are shown to be positive, whereas fourโ€bond co
