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

## Abstract ^13^C n.m.r. spectra of a series of __N__,__N__‐disubstituted thioamides have been recorded and signal assignments were performed. Separate signals are observed for methylene groups fixed on the nitrogen atom. Since the carbon atom __syn__ to the thiocarbonyl sulfur resonates at higher
