[ENA] type) is the main method of accounting for different nitrogen environments. Additionally, we see a reduction in 𝑅 𝑚𝑖𝑛∕2 for [#8X2H1+0:1], which corresponds to a hydroxyl oxygen. In previous work, we hypothesized that this change might be related to improved treatment of mixtures of alcohols and hydrogen bond acceptors like esters and ketones. We see those same improvements here, where alcohol/ester mixtures are initially underpredicted relative to experiment, but that underprediction is reduced after retraining, as shown in Figure .
