C02 - DFT Model
Model isotherms were calculated using the non-local prescription of Tarazona, employing molecular
parameters derived from the known bulk properties of carbon dioxide.
AR - Modified Density Functional Model
This model was produced in the same manner as the N2 Modified Density Functional model listed ear-
lier, except applicable to argon adsorbed at 87.3 K.
N2 - Tarazona NLDFT, Esf = 30.0K
