equil_enrich
estimates the isotopic enrichment or depletion,
ε^*_{LV} [-], given a known liquid-vapor equilibrium
fractionation factor.
1 | equil_enrich(alpha_VL)
|
alpha_VL |
Liquid-vapor equilibrium fractionation factor, α_{V/L} [-]. |
Enrichment is determined via (Horita et al. 2008):
ε^*_{LV} = (α^*_{LV} - 1)
Note that if enirchment/depletion associated with vapor-liquid equilibrium is desired, ε^*_{VL}, then one can either input α^*_{VL} or \frac{1}{α^*_{LV}} into this function.
