The observation of the rotational transitions of SH : has been extended to the 600 GHz region. The SH$ ion was generated by an electric dc discharge in the gas mixture of H2S and Hz in a hollow-cathode discharge cell. The J= 2-1, K= 0 and 1 transitions have been observed using a source-modulated sub

✦ Synopsis
Forbidden" rotational transitions of NH3 with the selection rules dl=O and k= f 1 t 7 2 were measured in the submillimeterwave region. The C, rotational constant for the lower component of the inversion doublet in the ground vibrational state is obtained from the observed spectrum as 186695.815 kO.053 MHz. The observed line intensity agreed well with that calculated from the centrifugal-distortion-induced dipole moment.
