The Study of Various Hydrogen-Bonded Complexes Using Pulsed, Fourier-Transform Fabry-Perot Microwave Techniques

A series of studies is presented in which microwave spectra are obtained for various hydrogen-bonded, gas phase complexes between small hydrocarbons and hydrogen halides or HCN. The pulsed Fourier-transform, Fabry-Perot technique is used allowing nuclear quadrupole coupling and other various hyperfine interactions to be observed in addition to the normal rotational spectra. Details of structure and binding are elucidated for the complexes from zero-field spectroscopic constants. Observation of the rotational Zeeman effect for complexes involving cyclopropane gives additional electronic distribution information for the complexes and is shown to indirectly give magnetic properties for cyclopropane. The complexes discussed include complexes between cyclopropane and HCl, HF, and HCN and complexes between ethylene or acetylene and HCl or HCN. Also, the extension of the pulsed Fourier-transform, Fabry-Perot microwave technique to study electronically excited triplet states is discussed.
