Abstract
Two inequivalent types of hydrogen bonds in KHSO4 were distinguished at temperatures 180–430 K using single-crystal 1H nuclear magnetic resonance (NMR) and magic-angle spinning NMR. From the 1H 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 T1 indicates that the energy transfer from the nuclear spin system to the surrounding environment is more facile.
