The Study of the Change of Fine-structures in Rotational Energy Transfer of NH2 ()

By using the high resolution dispersion spectra of NH2(~A2A1,090) 423(F1/F2) it is ob-served that the spin-rotational conservation transition is dominant for the parent levels. It con-firms the assumption that the electron is a spectator at single collision between open-shell and close-shell molecules. As to the daughter levels, the tendency for the conservation of the spin-rotation coupling of the parent level is found and may be explained by the long range interaction between those molecules.
