Henry's Law constant (water solution)
kH(T) = k°H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
k°H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar))
d(ln(kH))/d(1/T) = Temperature dependence constant (K)

Notes
1 | Normal isotopic mixture. |
2 | Deperturbed constants Coxon, 1974 allowing for the perturbation by the intersecting 0+ state arising from normal atoms (interaction matrix element ~ 360 cm-1), ωeye = -0.0673. The observed vibrational levels Coxon, 1974 are pushed down from their calculated positions by shifts ranging from 42 (for v=2) to 135 (for v=8) cm-1. |
3 | Deperturbed value Coxon, 1974; αe not given. Experimental Bv, Dv, Hv values for 2≤v≤8 in Coxon, 1974. |
4 | RKR potential curve Coxon, 1974. |
5 | Extrapolated from the lowest observed level (v'=2); see Coxon, 1974. Clyne and Coxon, 1967 give 16695 cm-1 based on low-dispersion spectra. |
