A technique which employs high resolution Fourier transform infrared spectroscopy is demonstrated for evaluation of hydrogen bond dissociation energies Do and De. Results for HCN--HF give aDo = 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 ofthermal functions of dimer formation in kJ/mol: aU;98.2 = 20.1(2), l:Jl;98.2 = 22.6(2), aG;98.2 = 59.4(2), M;98.2 = -0.1235.
Recent advances in the development and application of a highly sensitive near infrared FTIR supersonic jet spectrometer are reported. Investigations of: v1 OC‐HF; ν1, ν2 OC‐HCl; ν1 +, ν2 ± (HCl)2; ν1, ν1±ν21 Ar‐HCl and ν1 N2‐HCl will be presented. In specific cases, a direct comparison with corresponding spectra recorded using tunable near infrared laser supersonic jet and molecular beam absorption spectrometers will be made to illustrate the current capabilities and limitations of the FTIR supersonic jet spectrometer. As an example of the application of the technique to clusters, we report a study of the ν5 HCl asymmetric stretching band in the trimer, (HCl)3. Some preliminary studies of discharge‐generated species will also be reported using the jet spectrometer. The latter include: i) the investigation of vibrational hot bands in CO and ii) A2Π3/2,1/2→X2Σ+ rovibronic transitions in the CN radical.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
