Changes in the values of the valence angles in the alkaloid imidazole ring as a result of proton transfer from the acid mol­ecule to the imidazole N atom. It has been shown that the values of the α and γ valence angles are greater in the protonated forms (α1 < α2 and γ1 < γ2), while the value of the β valence angle decreases (β1> β2) (Gołdyn et al., 2021BB18).
