Abstract
The studies performed for right-handed (S)-4-(2-methylbutyl)-4′-cyanobiphenyl glass former using calorimetry (down to 0.35 K) and spectroscopy methods are reviewed. The substance reveals isotropic and cholesteric liquid phases, glass of cholesteric phase and two crystalline polymorphs, one of which transforms to glass. Two anomalies in heat capacity below 5 K and their relation to ordering of the molecules in three solid phases are discussed.

Notes
1In papers [14,16–19] the phase II has been called a metastable crystal, crystal I or C1 while the phase I – a stable crystal, crystal II or C2.
