✦ Synopsis


Contact time dependences of signal intensities in 29Si and "C CP/MAS NMR have been measured for kaolinite and kaolinitedimethylsulphoxide (DMSO) and kaolinite-DMSO-d, intercalation compounds. Cross relaxation times between 'H and 29Si and between 'H and "C 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.
