In response to our recent astrophysical discovery of highly excited circumstellar H¹²C¹⁴N gas via direct l-type transitions, we have conducted comprehensive and precise laboratory measurements of those transitions (v₂=1, ΔJ=0). The newly measured transitions cover the J-values from 15≤J≤35 and span the frequency range from 53 to 279 GHz. In addition, these new laboratory data are complemented by precision recordings of three medium ΔJ=1 (R-branch) transitions with J=19, 20, and 21 near 2 THz in the ground vibrational and the v₂=1 bending state. Third, we supply the v₂=1 vibrational satellites between 440 and 980 GHz of 5≤J_u≤11. The latter measurements were carried out in sub-Doppler resolution. All these new data are highly relevant to astrophysics.
