  Implicit electron-density solvation models based on joint density-functional
theory offer a computationally efficient solution to the problem of calculating
thermodynamic quantities of solvated systems from firstprinciples quantum
mechanics. However, despite much recent interest in such models, to date the
applicability of such models in the plane-wave context to non-aqueous solvents
has been limited because the determination of the model parameters requires
fitting to a large database of experimental solvation energies for each new
solvent considered. This work presents an alternate approach which allows
development of new iso-density models for a large class of protic and aprotic
solvents from only simple, single-molecule ab initio calculations and readily
available bulk thermodynamic data.
