An extension to the JCAMP-DX standard file format, JCAMP-DX V.5.01 (IUPAC Recommendations 1999)

Version 5.00 of the JCAMP-DX specifications were published for NMR and Mass Spectrometry file formats in Appl. Spectrosc. 47, 1093-1099 (1993) and App l. Spectrosc. 48, 1545-1552 (1994). Since publication of these protocols de velopments in spectroscopy have led to a large number of requests for addit ions for applications not originally covered. Following careful considerati on, it has become apparent that a few minor modifications will significantl y increase the range of possible applications. In addition, new data labels have been introduced to ensure that files are year 2000 compliant and allow for conformity with good laboratory practices (GLP). These modifications are detailed in this publication as well as exa mples of the official NTUPLE JCAMP-DX definition as applied to NMR data.
