We consider a simple system of interacting rotators and show that such a system could display properties of quantum crystals. The possibility of realizing new quantum system is discussed

It is shown that the magnetic properties of gamma -O2 are mainly determined by the intra-chain exchange interaction, i.e. gamma -O2 is a quasi-one-dimensional magnetic material. On the basis of the analysis of magnetic susceptibility, it was suggested that in liquid oxygen the gamma -phase-like structure persists as a short-range order.
