“…In crystals with the quasi‐linear OH···O moiety, the R value ~2.85 Å ( E HB ~25 kJ mol −1 ) limits the moderate and weak H‐bonds . At the same time, the O···O distance ~2.45 Å can be treated as the border between the short (strong) and extra strong H‐bonds …”

“…The formation of (Н 2 О⋅⋅⋅Н⋅⋅⋅ОН 2 ) + in aqueous acid solutions is accompanied by the appearance of absorption within 1700–1900 cm −1 . According to the IR‐intensive band, around 1720 cm −1 is a spectroscopic signature of the Zundel ion in liquid state. According to the IR active band, around 1750 cm −1 can be treated as the spectroscopic signature of the Zundel ion in the gas phase and molecular crystals.…”

“…Proton disolvates with the (quasi)symmetrical O···H + ···O unit (H 5 O 2 + , (Me(H)O···H···O(H)Me) + , (Et(H)O···H···O(H)Et) + etc., here Me═CH 3 and Et═C 2 H 5 ) are usually formed in these solutions . Their infrared (IR) spectra and structure in aqueous and methanol solutions of HCl were studied experimentally and theoretically, for recent reviews . Depending on ambient conditions, various proton hydrates are assumed to be generated in the aqueous solutions of HCl, namely, H 3 O + , H 5 O 2 + , H 7 O 3 + , Н 3 О + (3Н 2 О), and H 13 O 6 + .…”
