  The present work demonstrates a robust protocol for probing localized
electronic structure in condensed-phase systems, operating in terms of a
recently proposed theory for decomposing the results of Kohn-Sham density
functional theory in a basis of spatially localized molecular orbitals
[Eriksen, J. Chem. Phys. 153, 214109 (2020)]. In an initial application to
liquid, ambient water and the assessment of the solvation energy and the
embedded dipole moment of H$_2$O in solution, we find that both properties are
amplified on average -- in accordance with expectation -- and that correlations
are indeed observed to exist between them. However, the simulated
solvent-induced shift to the dipole moment of water is found to be
significantly dampened with respect to typical literature values. The local
nature of our methodology has further allowed us to evaluate the convergence of
bulk properties with respect to the extent of the underlying one-electron basis
set, ranging from single-$\zeta$ to full (augmented) quadruple-$\zeta$ quality.
Albeit a pilot example, our work paves the way towards future studies of local
effects and defects in more complex phases, e.g., liquid mixtures and even
solid-state crystals.
