## Abstract The molecular configuration and crystal structure of solid polycrystalline __N__,__N__′′‐diacetylbiuret (DAB), a potential nitrogen‐rich fertilizer, have been analyzed by a combination of solid‐ and liquid‐state NMR spectroscopy, X‐ray diffraction, and DFT calculations. Initially a pure

The relative axialÈequatorial position of spiro[4.5]decanes substituted in the 1,4-positions by oxygen or nitrogen were assigned by 15N and 17O NMR spectroscopy. The substituent, chemical exchange and steric e †ects upon the chemical shifts are discussed. A linear relationship between 15N and 17O wa
Pyridofuroxan ([1,2,5]oxodiazolo [3,4-b]pyridine 1-oxide) undergoes isomerization between the N1oxide and N3-oxide forms which can be observed by the 1 H, 13 C and 15 N NMR spectroscopy but not by 14 N and 17 O NMR at ambient and low temperatures. The rearrangement becomes slower at low temperatures
