Default spinning heating sample in MAS
spinning heating sample in MAS

there are two known mechanisms: friction heating( which may cause several degrees temperature increase) and induced AC current heating( in this paper:Electrical and ionic conductivity effects on magic-angle spinning nuclear magnetic resonance parameters of CuI. which can heat sample over 100 Celsius.)My question is, has any body seen this heating in MAS NMR?
