✦ Synopsis

THE discovery that the C13-H nuclear spin-spin coupling constant appears to be a linear function of the amount of s-character in the carbon orbital from which a C-H bond is formed1 has made direct estimation of hybridization possible for the first time. In cyclopropanela and certain cyclopropenes2 the C-H bonds are found by this technique to contain an unusually large amount of s-character, a reflection of increased p-character in the internal bonds which are forced by the geometry of the system to maintain abnormally small angles with one another. ' Cl34 ln several cyclic compounds in which C-C-C bond angles vary over a wide range. ' a N. Muller and D. E.
