Rotational analyses of the $c4\prime (0$) $\leftarrow X(0$) and $b\prime (1)\leftarrow X(0)$ bands of nitrogen have been completed. Interaction between the $c4\prime (0)$ and $b\prime (1)$ levels was completely analyzed by the deperturbation technique of $Kovacs.1$ The rotational constants derived with a matrix parameter, $H12=5.10$ $cm-1$, are: $$C^{\prime}{4}(0): T{0} = 104322.9 \ cm^{-1},\ B_{0} = 1.9308\ cm^{-1}, D_{0} =8.0 \times 10^{-5}\ cm^{-1}$$ $$b^{\prime}(1): T_{1} = 104417.7 \ cm^{-1},\ B_{1} = 1.1514 \ cm^{-1}, D_{1} = 1.7 \times 10^{-5} \ cm^{-1}.$$ The isotope bands of the same systems were also analyzed for $\mathrm{<mrow\; data-mjx-texclass="ORD">15</mrow>}N2$ and $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N15N$ and the results will be $discussed.1$
