✦ Synopsis

Values of the r e and α e equilibrium structural parameters of the PH 3 molecule have been determined on the basis of experimental data on the fundamental bands of the PH 2 D and PHD 2 species only, without any knowledge of the force-constant-type parameters of the PH 3 molecule. The functions of the equilibrium rotational parameters A e , B e , and C e have been determined. These functions are totally independent of the values of any resonance interaction parameters. Then these functions have been used to determine r e and α e constants. The obtained values r e = (1.416 776 ± 0.000 164) Å and α e = (93.56 ± 0.29) • differ a little from those found in the earlier literature.

## Abstract The cyanomethylidyne (CCN) has been the long‐standing subject of extensive theoretical and experimental studies on its structures and spectroscopies. However, there are few investigations on its reactivity. Our very recent theoretical work indicated that even with the simplest methane,
