Abstract

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.
