Simulation outputs:

InChI=1S/C4H8N2O3/c5-4(9)6-2-1-3(7)8/h1-2H2,(H,7,8)(H3,5,6,9) Parameter Value
Field strength 400.13(MHz)
RMSD of the fit 0.00432
Temperature 298 K
pH 7.4
InChI InChI=1S/C4H8N2O3/c5-4(9)6-2-1-3(7)8/h1-2H2,(H,7,8)(H3,5,6,9)
Note 1 H peaks are fitted. RMSD too high due to additional peaks on the N and O fitted but with a different peak width.
Note 2 Oscar Li

Help

To zoom into a region, draw a box around it.
Hover over the x/y-axis and use mouse-wheel to zoom in/out.
Hover over the x/y-axis hold down left-button to move around the spectra.
(De)activate a spectrum by clicking on its legend.
