Abstract
Measurements of the fine structure in the ammonia inversion spectrum have been extended into the millimeter wave region to the 16,16 line at 39941 mc/sec. The relative intensities and positions of the lines are compared with calculated values. The hyperfine structures of 15 lines have been measured. A systematic disagreement is shown to exist between the theoretical and observed separations of the hyperfine components. There is good agreement between the observed and calculated intensities of the hyperfine structure.
