The hyperfine structure of the 4\* + 4\* rotational transition of HDsOSe has been investigated using a high-rewlu-,--' tion beam-maser spectrdmeter. The deuteron quadrupole coupling constants, and the spin-rotatidn and the spin-. spin coupling constants invoiving the 11 and D nuclei have been evalua

Direct measurements of scattering cross sections for NHs in well-defined quantum states are made using a molcrular beam maser spectrometer. Cross sections are compared for a pure inversion state with those for a coherent superposition state for scattering gases He, Ar, Nz, N20, NHa, CFgH and CHaCN.T
Very high resolution measurements of hyperfinc structure on the P(l3) and R(15). 43--O, '11o+ -'xi transitions in iodine 127 were tnade using laser molecular beam spectroscopy. The observed linewidth was 30tkHz (fwhm) giving a resolution of 5 X lo-'o. The observed spectrum was fitted to obtain a qua
