Younes BEN TAARIT Receired 6 Februsq 1979 t3C NUR spectroscopy was used to invesrigte the ntture of carbon monoxide adsorbed on rransltion metal ions hosted in a synthetic bujasite type zeolite. The adsorbed CO species rots chxrxteriscd by ZI highly shielded carbon nudeus. Using the PopIe approximation for the paramagxtic shiriding term, the observed chemical shift 1x3s rationslised assuming the formation of a cationic carbonyl species aith an appreciable electronic trmsfer from the cxbon lone pair to the transition metal ion and ne$i$blr P back-bonding ifar ali.

## Abstract ^13^C‐NMR spectra of 20 cyanogenic glycosides have been measured in deuterium oxide. These compounds constitute representative examples of four groups of glycosides, namely the butyronitrile, propionitrile, mandelonitrile and cyclopentenoncyanohydrin glycosides. The well resolved signal
