Polyparameter linear free energy-relationships

As an alternative, Goss and coworkers have advocated modeling partitioning between the gas phase and aerosol particles using polyparameter linear free energy relationships (pp-LFERs) [ 12]. A pp-LFER for absorption into the bulk particle phase has the general form... 

McGowan molar volume of the chemical. These four chemical properties are examples of Abraham chemical descriptors, which are named after Michael Abraham, who pioneered this approach [13]. The parameters tibuik, buik, Cbuik, and rfbuik are empirically derived descriptors that are properties of the aerosol under consideration. These aerosol property descriptors are temperature-dependent and also dependent on relative humidity when adsorption is the dominant sorption mechanism. Polyparameter linear free energy relationships have been developed to describe absorptive partitioning between air and bulk aerosol particles [14,15], as well as adsorption to aerosol components such as mineral surfaces and salts [16,17] and to snow [18].
