Aluminum pure quadrupole spectra measured by photon echo ENDOR double resonance (PENDOR) are reported for crystals of YAlO3 doped with Pr3+ and for crystals doped with Eu3+. These spectra, which correspond to aluminum nuclei adjacent to a rare earth impurity, are compared to the results of a conventional NMR study of 27 Al in YAlO3. © 1982.
