摘要：

The effect of mixing by collisions on overlapping lines in the far-infrared (rotation) spectrum of gaseous ammonia was studied. A merging of the inversion doublets into single lines, similar to the collapse of the microwave inversion spectrum into a nonresonant spectrum, has been observed. The line shape has been analyzed using an adapted form of Ben-Reuven's theory and values of the damping and cross-relaxation parameters have been obtained for the rotational lines 3→4, 4→5, and 5→6.
