Abstract
Satellite lines have been observed near lines 11, 22, 21, 33, 44, 55, 66, and 76 in the inversion spectrum of ammonia. The relative intensities and displacements of these satellites are in excellent agreement with Van Vleck's recent theory. From the observed separations of the satellites from the main lines can be calculated the interaction energy between the electrical quadrupole moment of the nitrogen nucleus and the electric field of the ammonia molecule.
