Notes:
A technique which employs high resolution Fourier transform infrared spectroscopy is demonstrated for evaluation of hydrogen bond dissociation energies D0 and De. Results for HCN--HF give a D0=20.77(22) and De =28.77(45) kJ/mol which are compared with previously determined values obtained from microwave absolute intensity measurements and ab initio molecular orbital calculations. Rovibrational band information available for HCN--HF also permits evaluation of thermal functions of dimer formation in kJ/mol: ΔU(open circle)298.2 =20.1(2), ΔH(open circle)298.2 =22.6(2), ΔG(open circle)298.2 =59.4(2), ΔS(open circle)298.2 =−0.1235.
