چکیده
|
The v4 = 20 and v4 = 2-2 excited states of the oblate molecule pf3,lying near 693 cm-1,were reinvestigated by high-resolution ftir spectroscopy. assumed to be isolated,these levels were treated by applying different reduction forms of the effective rovibrational hamiltonian recently developed for the vt(e) = 2 vibrational state of a c3v symmetric top molecule,with models taking into account l-and k-type intravibrational resonances. parameters up to sixth order have been accurately determined. the unitary equivalence of the derived parameter sets in different reductions was successfully verified.
