The quadrupole hyperfine structure was resolved and analyzed for the vibrationally-ground state of the NH<SUB>2</SUB> species. The quadrupole coupling constants are: χ<SUB>aa</SUB>=2.34, χ<SUB>bb</SUB>=1.86, and χ<SUB>cc</SUB>=−4.20 MHz. The rotational constants obtained from the quadrupole corrected frequencies are as follows: <I>A</I>=5617.67, <I>B</I>=2593.88, and <I>C</I>=1777.04 MHz. The rotational constants of the ND<SUB>2</SUB> species in the vibrationally-ground state were also determined. By the use of the moments of inertia of both species, the non-planarity of this molecule was ascertained. The dipole moments of the NH<SUB>2</SUB> and the ND<SUB>2</SUB> species were determined to be 1.15±0.02 D and 1.13±0.01 D respectively.
