Abstract

Contact time dependences of signal intensities in ²⁹Si and ¹³C CP/MAS NMR have been measured for kaolinite and kaolinite-dimethylsulphoxide (DMSO) and kaolinite-DMSO-d₆ intercalation compounds. Cross relaxation times between ¹H and ²⁹Si and between ¹H and ¹³C have been estimated experimentally, which reflect the internuclear distances. Relaxation times have been calculated theoretically using reported crystal structure models, and we have discussed the validity of those models.
