Abstract
The 2-adamantanone molecule undergoes a phase transition from a disordered plastic phase (Fm3m, Z = 4) at room temperature to an ordered phase at lower temperature. The phase transition has been monitored by variable-temperature FT-IR spectroscopy. A large hysteresis effect ((~50 K) is observed between the cooling and heating cycles. From the numerous splittings observed, with non-degenerate species yielding at least four components, the low-temperature ordered phase is believed to have at least 4 molecules per unit cell.
