Carbon 13 NMR Prediction Overview |
C13 NMR and X-Nuclei Reference Database
With version 3 of NMRPredict, released in September 2006, NMRPredict now contains the world's largest collection of NMR data - over 424,632 records in total! The main NMRPredict program is supplied with 131,569 C13 records abstracted from the literature by Professor Robien and co-workers at the University of Vienna over the past 25 years. Three optional additional database available are:
- 131,414 C13 records from the SpecInfo collection licenced from Wiley

Over the last two years there has been a tremendous increase in the amount of data available with NMRPredict, from 96,788 C13 records in version 1 in 2004 to 117,571 records in version 2 in 2005 to 342,307 in June 2006 to 424,632 records in version 3 in September 2006.
In the next few years a dramatic expansion of the databases behind NMRPredict can be expected. The journals selected will cover mainly heterocyclic and medicinal chemistry in order to give reliable predictions for candidates for drug discovery (Lipinski's "Rule of Five").
The data is thoroughly checked and corrected at regular intervals which dramatically improves data quality.
Information contained in the data includes:
Data have been selected from a variety of journals including:
