Abstract
Single crystals of phenanthrene were found to exhibit a heat capacity anomaly and anomalous electrical effect in the vicinity of 72°C.1,2 A heat capacity anomaly was also found in this material in powder form. As a result of calculations3 and other measurements4 it is quite possible that the source of the anomalous behavior of phenanthrene is the crowded hydrogen atoms at the 4,5 positions of the molecule. A calorimetric survey was made of some other hydrocarbons with crowded hydrogens in the hope of finding materials which exhibit similar behavior.Keywords
