摘要：

Two inequivalent types of hydrogen bonds in KHSO4 were distinguished at temperatures 180-430 K using single-crystal H-1 nuclear magnetic resonance (NMR) and magic-angle spinning NMR. From the H-1 spin-lattice relaxation time in the laboratory frame, the hydrogen site H(1) with shorter hydrogen bonding is determined to have a longer relaxation time, while the H(2) with longer hydrogen bonds has a shorter relaxation time. The shorter T (1) indicates that the energy transfer from the nuclear spin system to the surrounding environment is more facile.
