## Abstract The vicinal ^3^__J__(CH~3~CCH) coupling constants were determined for a number of propylene derivatives and compared with the ^3^__J__(HCCH) couplings of the corresponding ethylenes. A linear regression analysis yielded the correlation ^3^__J__(CH) = 0.46 ×^3^ __J__(HH)+1.58 Hz, the c
