MILLIMETER AND SUBMILLIMETER-WAVE SPECTRUM OF HYDROGEN-PEROXIDE IN THE GROUND AND V(3)=1 VIBRATIONAL-STATES

The first measurements of the millimeter- and submillimeter (mm/submm) -wave rotational-torsional transitions in the upsilon(3) = 1 ground to rsional state (n = 0) of hydrogen peroxide are reported. The 149 newly measured transitions extend from 72 to 623 GHz in frequency and up to J = 32 and K-a = 3 in rotational quantum number. Additional measureme nts in the ground vibrational and torsional state around 1 THz are als o reported. These data, along with all previously published microwave, mm/submm-wave, and far infrared data in the ground and upsilon(3) = 1 vibrational state, along with recent infrared measurements, have been fitted simultaneously to their respective experimental uncertainties using a multi-state Hamiltonian that includes Fermi- and Coriolis-type interactions.
