Hindered internal rotation about the N–S bond in NN-dimethyltrichloromethanesulphinamide

Conformational interchange in acyclic hydrazines

“…Res., 5, 102 (1972). (b) The barrier to torsion through the conformation 17 could be quite large. However, this barrier would not normally be detectable by nmr since it can be bypassed by a lower energy path (via 18).…”

Nuclear magnetic resonance spectrometry

“…Such is the case for formyl proton coupling of formate esters (909, 976) and allylic couplings (587,815,646,1023). Such is the case for formyl proton coupling of formate esters (909, 976) and allylic couplings (587,815,646,1023).…”

Sulfur, An Important Element in my Life

“…In work carried out in collaboration with Hans Jørgen Jakobsen (Aarhus University, Denmark) we determined, by NMR measurements, the barriers to internal rotations around formal single bonds in a collection of sulfen-, sulfin-and sulfonamides [176,177] as well as in 5-(dimethylamino)-1,3,4-oxathiazole 3,3-dioxide 291 [178].…”
