Abstract: | The vicinal 3J(C H3C?CH ) coupling constants were determined for a number of propylene derivatives and compared with the 3J(H C?CH ) couplings of the corresponding ethylenes. A linear regression analysis yielded the correlation 3J(CH) = 0.46 ×3 J(HH)+1.58 Hz, the correlation coefficient being 0.956. |
