Table 1
Measured visible refractive indices, n633, and estimated densities, ρ, of the ices of H2O, CO2, and CO.
| T = 10 K | H2O | CO2 | CO |
|---|---|---|---|
| n633 | 1.205 ± 0.005(a) | 1.235 ± 0.005(a) | 1.250 ± 0.005(a) |
| a(À3) | 1.48(b) | 2.46(c) | 1.95 (d) |
| L (cm3/g) | 0.207(b) | 0.141(c) | 0.176 |
| ρ (g/cm3) | 0.63 ± 0.02 | 1.06 ± 0.03 | 0.91 ± 0.03 |
Notes. The ices were formed by background gas deposition at 10 K in the experiments of this work. The polarisabilities, α, used for the estimation of the densities with equation 6 and the corresponding Lorentz-Lorenz coefficients, L, are also given in the table. (α)This work. (b)Brown & George (1996). These authors reported the Lorentz-Lorenz coefficient, L = 0.207 cm3/g from which α is calculated. (c)Domingo et al. (2015). (d)Ron & Schnepp (1967).
