✦ Synopsis

0 nuclear quadrupole resonance frequencies and lineshapes have been measured in naturally abundant polycrystalline samples of potassium hydrogen diacetate and sodium hydrogen diacetate. In sodium hydrogen diacetate all hydrogen-bonded oxygen sites are equivalent while in potassium hydrogen diacetate two clearly distinguishable oxygen sites have been observed with different O-H distances. Thus the O-H--O hydrogen bonds are symmetric in sodium hydrogen diacetate and asymmetric in potassium hydrogen diacetate. The nuclear quadrupole resonance frequencies of s9K and *3Na have also been measured.
