COLMAR1d database search tool

• By default, this page will list all records in our COLMAR1D database. The COLMAR1D database contains spin system matrices and predicted spectra at various field strengths for more than 1100 metabolites. Most of the metabolites are sourced from the Gissmo database without modification. Additionally, some experimental spectra have been obtained from the Human Metabolome Database (HMDB) and our own measurements, followed by spin system matrix optimization.
• You can list and search the COLMAR1D database.
• Click on the compound ID to add it to the selected list, which can then be saved as a user-defined subset for customized queries.
