## Abstract The ^13^C and ^1^H spectra of a series of aromatic ketones, ethers and ketoโ€ethers 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, 6โ€methoxyphenalenone,
