Abstract

The JCAMP-DX format provides a standard for the exchange of data on IR spectra. Extensions of this format to other spectral data are being developed. Spectral data should always be accompanied by information on the chemical structure of the investigated compounds. The JCAMP-CS format provides definitions for exchanging information on the composition and the stereochemistry, as well as on the 2D and 3D atomic coordinates, of chemical structures. Where possible, the standard was designed to adhere to the conventions of JCAMP-DX. In addition, care was taken to make as simple as possible the conversion to other formats in use for representing chemical structures.
