The 13C chemical shifts of cis-and trans-benzylidenepropylamine and substituted benzylideneanilines were analysed after additons of Eu(fod),. The cisltrans ratio increases as the amount of lanthanide shift reagent increased. The cis isomers showed large lanthanide-induced shifts, whereas the trans i
## Abstract The ^13^C and ^1^H spectra of a series of aromatic ketones, ethers and ketoโethers were studied using the lanthanide shift reagent (LSR) Yb(fod)~3~ and the data analyzed using the lanthanide induced shift (LIS) ratio method. Studies were carried out on phenalenone, 6โmethoxyphenalenone,
