Normalized histogram of sampled NH₃ BE (in kJ/mol), fitted with a GMM using scikit-learn algorithm (Pedregosa et al. 2011). Previously reported NH₃ BE values onto water ice analogs with diverse simulation methods are given on top. Horizontal intervals report on published BE dispersions, while vertical dashed lines relate to works focusing on single BE values. Methods used in each work are discussed in the text. The BE value on crystalline ice from Ferrero et al. (2020) is also given (plain gray line). Ref: [1] Ferrero et al. (2020); [2] Duflot et al. (2021); [3] Tinacci et al.
