Using the Theil-Sen estimator, we found that the point estimate for = was 0.484 with a 95% CI of [0.476, 0.488]. In other words, B3LYP/aug-cc-pV(T+d)Z together with PCM benzene yields molecular dipole moments that are nearly "halfway between" calculated gas phase and PCM water dipole moments. It is worth noting that dipole moments for the IPolQ and IPolQ-Mod charge models -to be discussed in greater detail in the next section -would be obtained by assuming that = is exactly ½. Therefore, as we will argue in the Discussions and Conclusions section, the dipole moments -and charge distributions -obtained with these electronic structure methods are likely "in the neighborhood of correct" for use in condensed phase simulations.
