Provisional Recommendation - Definition of the Hydrogen Bond
The International Union of Pure and Applied Chemistry is pleased to announce the following Provisional Recommendation.
Abstract:
The task group recommends the definition given here for the hydrogen bond. The short definition is followed by a list of experimental and/or theoretical criteria, which can be used as evidence for the presence of the hydrogen bond. Finally, some characteristics that are typical of hydrogen bonded systems are given. A brief explanation of the terms used is provided after the definition. Moreover, several footnotes (indicated by F#) have been added and these are given at the end. These footnotes are intended to give more explanation for the sake of clarity and completeness. The task group has also produced a comprehensive technical report, which appears elsewhere in this issue of Pure and Applied Chemistry. This report provides a summary of the past work on hydrogen bonding and also the rationale for the proposed definition.
IUPAC seeks your comments
Comments should be submitted by 31 March 2011. The text of the Provisional Recommendation can be downloaded from here. Comments should be sent to Professor E. Arunan at arunan@ipc.iisc.ernet.in.
Provisional Recommendations are drafts of IUPAC recommendations comprising topics on terminology, nomenclature, and symbols. These recommendations are made widely available to allow interested parties to comment before the recommendations are finally revised and published in Pure and Applied Chemistry.
