Description:
The analysis of the fully resolved Nitrogen hyperfine structure of
N2D+ (1-0) observed toward L183, together with laboratory
measurements of the same molecular transition, allowed an accurate
determination of the hyperfine constants of both outer and inner
Nitrogen. In addition, accurate rotational and centrifugal distortion
constants were derived from submillimeter-wave laboratory
measurements. The Tables list calculated hyperfine frequencies of
J+1⟵J transitions, with J in the range 1-11, which occur in the
millimeter- and submillimeter-wave region.
