Advanced molecular matching service powered by intelligent NMR spectrum analysis. Identify complex components by matching experimental spectra against our comprehensive database.
"Precision in every peak, confidence in every match."
OmSIE/NMR supports multiple NMR spectrum types with advanced algorithms for accurate and efficient molecular identification.
Match one-dimensional carbon-13 NMR spectra with optional carbon type classification (s, d, t, q) for enhanced specificity in molecular identification.
Launch TaskTwo-dimensional heteronuclear correlation matching with proton-carbon connectivity analysis, supporting intensity-based type classification for CH&CH3/CH2 groups.
Launch TaskSimultaneous matching of 13C and HSQC spectra for comprehensive structural validation, leveraging multi-dimensional constraints for higher confidence results.
Launch TaskAdvanced long-range heteronuclear correlation analysis incorporating HMBC connectivity constraints for complex structure elucidation and stereochemical assignment.
Launch TaskRefine results with molecular weight ranges, carbon count filters, substructure searches, similarity matching, and organism-specific constraints for targeted discovery.
