Properties of Solid Molecular Hydrogens as a Function of Density and Ortho-Para Concentration as Studied by Raman Scattering

摘要

The results of Raman scattering experiments on solid molecular hydrogens as a function of density and ortho-para concentration are presented. The Raman scattering spectra of double rotational transitions are discussed. These spectra are taken as a function of ortho-para concentration in zero pressure H sub 2 and as a function of density in both H sub 2 and D sub 2 up to 5000 atm. at the melting line. Double rotational transitions are also observed in the liquid phases of H sub 2 and D sub 2 at zero pressure. Measurements of the density dependence in H sub 2 and D sub 2 and the isochoric temperature dependence of these frequencies are discussed. The dependence on the ortho-para concentrations of several libron properties is given. (Atomindex citation 09:384303)
