Abstract
We have measured and analyzed the emission spectrum of HNC from 400 to $4100 cm^{-1}$. The HNC was observed as an equilibrium mixture of HCN and HNC in a fused quartz cell heated to 1350 K. The three fundamental bands and many hot bands of HNC were measured with resolutions ranging from $0.006 cm^{-1}$ for the lowest fundamental to $0.033 cm^{-1}$ for the other two. Thirty-five different vibrational and vibrational angular momentum states were measured. High rotational levels, in some cases up to $J = 50$, were also measured. Now all the quadratic contributions to the vibrational and rotational term values have been measured, as well as some higher order contributions.
