A quantum Hamiltonian, starting from the electric quadrupole-quadrupole interaction between molecules in solid hydrogen, is constructed for an ortho-para hydrogen mixture with the quadrupolar momenta of the orthohydrogen species randomly frozen out. With use of this Hamiltonian, the effective functional Landau-Ginzburg-Wilson Hamiltonian has been derived. A field-theoretic renormalization-group analysis leads to a conjecture that the system undergoes a discontinuous transition from the orientationally disordered to the quadrupolar glass phase. This transition is smeared out by the influence of the random local crystal field.
