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

The complete assignment of the proton chemical shifts for kxo-norborneol was obtained from a COSY experiment at 250 MHz. Using these assignments the conformation of this molecule in solution was studied using the lanthanide-induced shift technique, applying a new three-site lanthanide complexation m

## 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,
