The n → π* transition of the carbonyl group has been studied in solvents of varying degree of polarity and hydrogen-bonding ability, in a number of aliphatic carbonyl derivatives. Evidence for hyperconjugation of the alkyl groups in the electronically excited states of molecules has been presented.

Quasi Binary System

The melting diagram of the quasi-binary system NH3-HF between the limits NH4HF2 and HF was redetermined. The compounds NH3 · 4HF, NH3 · 5HF and NH3 · 8HF with melting points of 26, -14 (dec.) and -95 °C (dec.), respectively, were established as the stable phases. Their crystal structures were determined as those of ammonium hydrogen fluorides NH4[F(HF)4], NH4[F(HF)4] and NH4[HF2(HF)3] · 3HF with extended N-H···F and F-H···F hydrogen bonding.

Intramolecular Hydrogen

Certain ortho-substituted acetanilides exhibit proton magnetic resonance signals at unusually low field for the amido proton and the aromatic proton adjacent to the acetamido group. This effect, explicable in terms of intramolecular hydrogen-bonding, has been observed for nitro, carbonyl, sulfamoyl, and sulfonyl substituents. Solvent effects are discussed.
