We recently discovered an error in the code that led to incomplete addition of the polarizable continuum model (PCM) solvation field. We have corrected the issue and have cross-checked the results by comparing to an independent NEO-PCM implementation in Q-Chem. Here we provide updated versions of the figures and tables that were impacted. An updated version of the entire Supporting Information is also provided.

Ground State NEO-PCM

When placed in a PCM solvent, the protonic zero-point energy (ZPE) of HCN, here defined as the difference between the NEO–DFT and conventional DFT energies, decreases as a function of permittivity, as shown in Figure 1.

Figure 1. Energetics of HCN in a variety of solvents with a classical proton description (circles) and with a NEO protonic wave function (crosses). The protonic zero-point energy is shown with triangles.

As shown in Figure 2, the NEO C–H distance, defined as the distance between the position of the classical carbon nucleus and the expectation value of the proton position, increases with increasing solvent permittivity, in conjunction with an increased molecular dipole moment.

Vibrational Solvatochromic Shifts

The C–H vibrational frequencies and solvatochromic shifts from a neutral environment to water for the formate ion obtained with the real-time NEO Hartree–Fock (RT-NEO-HF) method and the second-order vibrational perturbation theory (VPT2) approach are given in Table 1.

As stated in the main paper, the VPT2 results were obtained using the same split electronic basis set. After performing a full geometry optimization, the masses of the carbon and oxygen atoms were set to artificially high values for the normal mode and VPT2 frequency calculations in order to mimic the NEO calculations. The resulting frequencies are provided in Table 1. Performing VPT2 on the whole molecule without artificially high masses in vacuum provides a stretch frequency of 2544 cm–1.

Solvated Proton Transfer Dynamics

The distances between the expectation value of the quantum proton position and the donor and acceptor oxygens for excited state proton transfer in oHBA are shown in Figure 5 for simulations both in vacuum and in water. The proton transfers to the acceptor oxygen approximately 4.6 fs after excitation in both vacuum and water.

The distance between the expectation value of the transferring proton position and the donor oxygen (blue) and acceptor oxygen (red) is given as a function of time. The crossing for both cases is marked with the vertical dashed line.
