In this document, we define a data exchange format initially formulated from discussions of an International Union of Pure and Applied Chemistry (IUPAC) limited-term task group at the 35th Royal Society of Chemistry-ESR conference in Aberdeen 2002. The definition of this format is based on the IUPAC Joint Committee on Atomic and Molecular Physical Data Exchange (JCAMPDX) protocols, which were developed for the exchange of infrared spectra and extended to chemical structures, nuclear magnetic resonance data, mass spectra, and ion mobility spectra. This standard of the JCAMP-DX was further extended to cover year 2000 compatible date strings and good laboratory practice, and the next release will cover the information needed for storing n-dimensional data sets. The aim of this paper is to adapt JCAMP-DX to the special requirements for electron magnetic resonance (EMR).
Pure and Applied Chemistry is the official monthly Journal of the International Union of Pure and Applied Chemistry (IUPAC), with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union.
