Such NMR records will also be optionally exported and imported by NMR software packages such as computer-assisted structure elucidation software and could be submitted with manuscripts for publication. An NMR record is a compressed folder including the NMReDATA file and all related 1D and 2D spectra (see Figure 1) including the raw data (i.e., the FIDs and all the acquisition and processing parameters).

īecause of the need to keep both the NMReDATA and the associated spectra together to allow for verification of their consistency, we have also introduced the concept of “NMR record”.

This contrasts with the current unsatisfactory situation where NMR parameters are dispersed in peak lists, tables of correlations, and low-quality image-based spectra typically located in supplementary material, commonly in PDF format only and thereby making it difficult for both humans and computers to access and assess the data. Simply opening the NMReDATA file will permit a user to interrogate and confirm the assignments associated with the signals in the spectra. More importantly, it will constitute an easier way for the inspection and verification by reviewers because the data will be suitable for submission to scientific journals.

These formatted NMReDATA will facilitate the accessibility and exchange of the partial or full structure assignment within the chemistry community. These electronic reports will be generated by software assisting chemists in the interpretation of spectra or by using tools to create them in the case where the spectra were interpreted using “paper and pencil.” The commercial software providers Bruker, Mestrelab Research, Advanced Chemistry Development (ACD/Labs) and the non-commercial software platforms nmrshiftdb2 and, have all committed to use the format in future releases of their products. Herein, we introduce a file format to effectively associate these NMReDATA with the assigned structure. The reliability of the structure determination depends heavily on the accuracy and extent of the NMReDATA, which needs to be reported in a format compatible with a maximum number of software packages. This format is easily readable by humans and computers and provides a simple and efficient way for disseminating results of structural chemistry investigations, allowing automatic verification of published results, and for assisting the constitution of highly needed open-source structural databases.Įxploiting the NMR spectra of compounds consists of extracting the NMR parameters, which we call NMReDATA (for “NMR extracted data”), including chemical shift values, scalar coupling constants, and 2D correlations, and assigning them to a chemical structure. The association of an NMReDATA file with the raw and spectral data from which it originates constitutes an NMR record. The file format is an extension of the existing Structure Data Format, which is compatible with the commonly used MOL format. These NMR parameters, which we shall call NMReDATA (for nuclear magnetic resonance extracted data), include chemical shift values, signal integrals, intensities, multiplicities, scalar coupling constants, lists of 2D correlations, relaxation times, and diffusion rates.

A new format is therefore introduced to associate the NMR parameters extracted from 1D and 2D spectra of organic compounds to the proposed chemical structure. Even though NMR has found countless applications in the field of small molecule characterization, there is no standard file format available for the NMR data relevant to structure characterization of small molecules.
