Detailed Description

Virtual base class for a species with a pressure dependent standard state.

Virtual base class for calculation of the pressure dependent standard state for a single species

Class PDSS is the base class for a family of classes that compute properties of a set of species in their standard states at a range of temperatures and pressures. The independent variables for this object are temperature and pressure. The class may have a reference to a SpeciesThermoInterpType object which handles the calculation of the reference state temperature behavior of the species.

This class is analogous to the SpeciesThermoInterpType class, except that the standard state inherently incorporates the pressure dependence.

The class operates on a setState temperature and pressure basis. It only recalculates the standard state when the setState functions for temperature and pressure are called.
