WebSelf-Consistent Reaction Field. Self consistent reaction field (SCRF) approaches [44], for example with the conductor-like screening model (COSMO) [45], can be used to predict the pKa values of acids in aqueous and other solutions to connect the gas phase values with those of the condensed phase.
