Additionally, we find that the variance of data from the regression line is comparable to the HF/aug-cc-pV(T+d)Z data (Figure ). Finally, we examined the overpolarization of B3LYP/aug-cc-pV(T+d)Z with PCM water (ε = 78.4). In this higher dielectric environment, the calculated dipole moments are 1.363 times larger (95% CI: [1.324, 1.400]) than experimental gas phase dipole moments (Figure ), suggesting a characteristic overpolarization that is more than 4 times the HF/6-31G* result. It is additionally apparent that some of the calculated dipole moments are further from the regression line for PCM water than for PCM benzene (Figure ).
