We have studied the microscopic structure of a proton-irradiated KH 2PO4 (KDP) single crystal. In solids, the strong dipolar interaction is an obstacle to observing the weaker chemical shift that porvides information on the molecular structure. Therefore, the dipolar interaction must be removed to observe the chemical shift. Our 1H combined rotation and multiple pulse spectroscopy (CRAMPS) nuclear magnetic resonance (NMR) measurement indicates that proton irradiation causes an increase in the isotropic chemical shift, implying a fine structural modification of the O-H⋯O hydrogen bonds in the paraelectric phase.
