Spectroscopic Determination of Hydrogen Bond Energies

Unified classification of non-covalent bonds formed by main group elements: a bridge to chemical bonding

“…The CNF acts as a better fluorine bond than NCF and NCCF. The slope for the F halogen-bond was found to be 875 (71). The strength of the halogen bonded complexes decreases in the order of I 4 Br 4 Cl 4 F. The introduction of supersonic expansion methods allowed Klemperer and co-workers to study the rotational spectra of HFÁ Á ÁClF 92 and HFÁ Á ÁCl 2 93 in effective isolation by utilising molecular beam electric resonance spectroscopy.…”

“…The binding energy of non-covalently bonded complexes can be determined using various spectroscopic techniques, as summarized by Goswami and Arunan 71 in a recent book chapter. However, in order to obtain correlation plots, we need a large number of data points for each non-covalent bond.…”
