Hello All:



I recorded 1H and 15N spectra of 15N-labeled urea in DMSO.

Both 15N-decoupled 1H and 1H-decoupled 15N spectra have single peak.

Without decoupling, both 1H and 15N spectra show a small splitting of ~4 Hz (see attached pictures).

Does anybody have an explanation of the splitting pattern?



Thanks,
