MOLECULAR BEAM ELECTRIC RESONANCE SPECTRUM OF HF DIMER

Abstract

Using an expansion nozzle source, beams of ArXe, XeHCl, $(HCl)_{2}$ and a series of HF polymers have been observed. XeHCl, $(HCl)_{2}$ and $(HF)_{2}$ have dipole moments large enough to give refocussing in a quadrupole electrostatic field. Microwave and radiofrequency resonances have been observed for $(HF)_{2}$ and $(DF)_{2}$. The spectrum does not fit rigid rotor models. This talk will be a progress report on the spectral assignment of these species.
