    Description / Table of Contents: Hydrogen-bonds, XII. Intramolecular Hydrogen Bonding in 1.2-, 2.3- and 1.8-Hydroxy-, Amino- and Nitro- Naphthalene DerivativesThe strength of intramolecular H-bonds is decreased in nitro-naphthols in the order 1.2, 2.3 and 1.8 as measured from the shifts of the OH-streching frequencies in the i.r. spectra. Among the amino-naphthols the OH—N-bond is strongest in the 1.8-derivative. The occurence of H-bonds in nitro-naphthylamines has been reinvestigated. The effects of geometry on the strength of intramolecular H-bonds are discussed.
    Notes: Gemessen an der langwelligen Verschiebung der OH-Bande in den IR-Spektren wird die intramolekulare H-Brücke bei Nitro-naphtholen in der Reihenfolge 1.2 〉 2.3 und 〉 1.8 immer schwächer; im Gegensatz dazu liegt bei den Amino-naphtholen im 1.8-Derivat die stärkste OH—N-Brücke vor. Die H-Brücken bei 2.3- und 1.8-Nitro-naphthylamin werden erneut untersucht und die geometrischen Voraussetzungen für die Festigkeit solcher H-Brükken besprochen.
