equil_enrich: Liquid-vapor equilibrium enrichment factor

Description Usage Arguments Details Value

Description

equil_enrich estimates the isotopic enrichment or depletion, ε^*_{LV} [-], given a known liquid-vapor equilibrium fractionation factor.

Usage

1
equil_enrich(alpha_VL)

Arguments

alpha_VL

Liquid-vapor equilibrium fractionation factor, α_{V/L} [-].

Details

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.

Value

A numeric value
