摘要: Quantum mechanical lineshapes of collision-induced absorption (CIA) at different temperatures and light scattering (CILS) room temperature are computed for gaseous molecular hydrogen using theoretical values induced dipole moments pair-polarizability trace anisotropy as input. Comparison with measured spectra absorption, isotropic anisotropic shows satisfactory agreement, which the uncertainty in measurement its spectral is seen to be large. Empirical models moment reproduce experimental first three more closely than fundamental theory also given. Good agreement between both obtained when potential constructed from thermophysical, transport, total cross-section spectroscopic properties used. Also, use new lattice dynamic calculations yields good results several solid hydrogen.
