Measurements were made in CCI, of the formation constant K,, of the 1 : l hydrogen-bonded complexes between the reference donor 4-fluorophenol and the intramolecular hydrogen-bonded systems I (one lone pair on heteroatom Y, one intramolecular hydrogen bond: 8-hydroxyquinaldine and 2-(2-hydroxyphenyl

An nmr spectral comparison of a model cyclic pentapeptide cyclo(G1y-Pro-Gly-D-Phe-Pro) with an analogous pseudopeptide has been made. The pseudopeptide contains a $[CH2S] amide bond replacement a t the only amide linkage that, in the model, is not involved in an intramolecular hydrogen bond. Both pr

The intramolecular hydrogen bonding (chelation) of salicylaldehyde, methyl salicylate, N , Ndimethylsalicylamide and 2-hydroxyacetophenone was studied by IR spectroscopy in different phases used for partition coefficient determinations. The extent of chelation was found to be highly sensitive to the
