In this work correlation dependencies between hydrogen bond energy ΔE for complexes with F–H⋯F hydrogen bond and their spectroscopic characteristics of the IR and NMR spectra are presented. We considered 26 complexes in a wide hydrogen bond energy range 0.2–47 kcal/mol. For each complex we calculated complexation energy (MP2/6-311++G(d,p)), IR spectroscopic parameters (FH stretching frequency ν FH stretching frequency in local mode approximation ν _LM at MP2/6-311++G(d,p) level) and NMR parameters (chemical shift of hydrogen δ _H and fluorine nuclei δ _F, Nuclear Independent Chemical Shielding and spin-spin coupling constants ¹J _FH, ^1hJ _H…F, ^2hJ _FF at B3LYP/pcSseg-2 level). It was shown that changes of parameters upon complexation, i.e. changes of the stretching frequency in local mode approximation Δν _LM, change of the proton chemical shift Δδ _H and change of the absolute value of spin-spin coupling constant ¹J _FH could be used for estimation of corresponding hydrogen bond strength. Furthermore, we build correlation dependencies between abovementioned spectroscopic characteristics and geometric ones, such as the asymmetry of bridging proton position q ₁ = 0.5·(r _FH – r _H…F).
