Accurate predictions of charge excitation energies of mols. in the disordered condensed phase are central to the chem. reactivity, stability, and optoelectronic properties of mols. and critically depend on the specific environment. Herein, we develop a stochastic GW method for calculating these charge excitation energies. The approach employs maximally localized electronic states to define the electronic subspace of a mol. and the rest of the system, both of which are randomly sampled. We test the method on three solute-solvent systems: phenol, thymine, and phenylalanine in water. The results are in excellent agreement with the previous high-level calculations and available exptl. data. The stochastic calculations for supercells containing up to 1000 electrons representing the solvated systems are inexpensive and require ≤1000 central processing unit hrs. We find that the coupling with the environment accounts for ∼ 40% of the total correlation energy. The solvent-to-solute feedback mechanism incorporated in the mol. correlation term causes up to 0.6 eV destabilization of the quasiparticle energy. Simulated photoemission spectra exhibit red shifts, state-degeneracy lifting, and lifetime shortening. Our method provides an efficient approach for an accurate study of excitations of large mols. in realistic condensed phase environments. (c) 2021 American Institute of Physics.
