“…We find P(H2)= (2-010 _+ 0.010)cm 3 and P(HD)= (2.018 + 0'003) cm37 in good agreement with previous experimental [23,25] and theoretical [27] determinations. It should be noted and is also confirmed by results on D2 [25] that the molar polarization is practically independent of the degree of deuteration. On solidifying, the dielectric constants increased by about 4%.…”

“…The dielectric constants of the liquid hydrogens, H2 and HD, studied in this work increased almost linearly with decreasing temperatures in agreement with previous dielectric investigations [23][24][25]. Using the densities p of these liquids as tabulated by Woolley (1)…”

“…On solidifying, the dielectric constants increased by about 4%. In contrast to a previous report [25] this effect was quite reproducible and therefore well defined values for the dielectric constants were obtained in the solid states. Using the molar volumes of n-H 2 (22.91 cm 3) and of HD (20.58 cm 3) [1] together with the electronic contributions to the permittivities yields P(Hz)/P(HD ) = 1.025 -L-_ 0.005.…”

The solid and liquid phases of hydrogen, n-H 2 and HD, and methane, CHD 3 and CH3D, have been studied by dielectric measurements. It is found that increasing deuteration has only a minor effect on the molar polarization of hydrogen, but that it leads to a significant decrease of the polarizabilities of the liquid methanes. The dipole moments of the partially isotope substituted molecules have been determined in the solid state. For HD a local field corrected moment of 0"78 mD is found, for CHD3 and CH3D the moments are 4.3 and 4.1 mD, respectively.

“…Kogan et al [66] measured the dielectric constant of liquid n-D, along the saturated vapor-pressure curve from the triple point to 20.4 K. From their 12 data points and the corresponding liquid molar volumes computed from eq (8), we calculate an average value of P E =7.9371 X 10- This result agrees with those derived from similar data reported by Constable et al [67] in the range 18 To our knowledge, the only solid phase measurement on n-D, is that published by Wallace and Meyer [52].…”

Analytical expressions are derived for the melting line and liquid equation of state of normal deuterium near the triple point. Melting pressures were measured between the triple point and 20.4 K. These results combined with existing pressure measurements along the saturated liquid-vapor curve fix an accurate value. Ttp =j118. 723 K, for the triple-point temperature. Data for the isothermal compressibility and thermal expansion coefficients of the liquid were taken over the temperature and pressure ranges 18.8 to 21.0 K and 4 to 70 bar, respectively. The liquid molar volume was measured at nine points below 20.4 K. All liquid PVT data are shown to be internally consistent. Measurements of the volume changes on melting are also presented. The heat of fusion and the solid molar volume at melting are deduced from these data. Also included are detailed comparisons of our results with existing data. A critical appraisal is given of all measured thermodynamic quantities in this regime.
