The ^13^C NMR of fourteen spiro cyclic glycidic esters and two amides have been investigated.

The 13C NMR spectra of alcohols and their corresponding nitrate esters were investigated. An empirical equation is suggested for the change in the chemical shift due to substitution by a nitro group. The spin-lattice relaxation times are reported.
## Abstract Carbon chemical shifts of cyclic dimethylene compounds were determined and interpreted. It is suggested that steric compression leads to additional shielding of the __exo__‐methylene group, the chemical shifts of this group being a useful measure of the amount of steric hindrance.
## Discussion 73Ge is an esoteric nucleus as far as NMR spectroscopy is concerned, chiefly because of its large quadrupolar moment, which tends to cause excessive broadening of signals, and there are many fewer reported data than for other Group IVB elements.' So far, to our knowledge, no attempt
