Dipolar-dephasing with high power 2~M irradiation yields 1H MAS NMR echo spectra of 'aluminium-unconnected' hydroxyl groups in dehydrated zeolites. The aluminium-connected SiOHAI and AIOH hydroxyls can be observed as the difference spectra. The technique increases the number of OH lines in the 1H NM
