The pure rotational spectrum of methoxyacetonitrile, CH30CH,CN, has been investigated in the 8-40 GHz region. Spectra of thega~rcl~e and trans conformers, with respect to rotation about the 0-CH, bond, have been assigned. The rotational constants for the ground vibrational state are (in MHz) [Traduit par le journal]Can.

The n~icrowave spectra of morpholine and N-deuteroniorpholine have been investigated within the 8 to 40 GHz region. For both the normal and the deuterated species, strong a-type spectra which are due to the chair conformer with an equatorial imino group were recorded. The ground vibrational state rotational constants and quadrupole coupling constants are (in MHz) The value of a,, and the direction of 11 with respect to the n and c principal axes confirm that the observed spectrum is that of the chair equatorial conforn~er of morpholine.
