The heat capacities of a pyridinium tetrafluoroborate (PyHBF 4 ) crystal were measured in the temperature region between 6 and 372 K with an adiabatic calorimeter. The crystal showed two first-order phase transitions with heat-capacity peaks and wide tails on both the low-and high-temperature sides

A T1 minimum at 216 K for Larmor frequency 90 MHz has been detected and for this minimum no analogous T, minimum according to the known quadratic dependence of the Larmor frequency 25 MHz is found. The analysis leads to the conclusion that this T1 minimum is a result of the relaxation of protons via
