Rotational Spectra of Symmetric Top Molecules in Ground andDifferent Vibrational Excited States, and Phenomenon of Resonance – Applying in CF3CCH

Masoud Motamedi

This paper deals with review of exploration of resonance in symmetric topmolecules in different vibrational excited states, vt = n (n =1, 2, 3, 4). Calculations for CF3CCH shows that resonance take place at [Eq. 20] and [Eq. 21] for v10 = 2 and v10 = 3 respectively. In order to account for splitting about 3 MHz for the - 2 series in v10 = 4 is necessary to introduce the element {J, k, l |f24| J, k + 2,l − 4} in fitting program.
