## Abstract The ^13^C and ^1^H spectra of a series of aromatic ketones, ethers and keto‐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, 6‐methoxyphenalenone,

The adoption of a rigorous error analysis of L.I .S. 's allows the non-pseudo-contact components of the Yb(fod)a induced shifts in benzaldehyde and thiophen-Z-aldehyde to be isolated. They are largest at the carbonyl carbon and at the ortho and pam carbons and appear to be entirely due to complexat
