The millimeter-wave rotational spectrum of CF3CCD in the excited vibrational state v10=2

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

“…The Hamiltonian is set up for a symmetric top molecule like CF 3 CCH [2, 11]. This rotationvibrational Hamiltonian has two different blocks belong to the different ℓ = + 1 and ℓ = −1 series.…”

“…The diagonal matrix elements are given by equation (7). This Hamiltonian can set up for a symmetric top molecule such as CF 3 CCH, CF 3 CCD, CF 3 CN, and OPF 3 [10, 20–30]. It has three different vibrational blocks related to ℓ = 2, 0 and −2 Figure 6.…”

“…These situation have been previously observed only for PF 3 , v 4 = 1 [3], for CF 3 H and CF 3 D, v 6 = 1 [4], CF 3 Cl, v 6 = 1 [5] and CH 3 CF 3 , v 12 = 1 [6]. The rotational spectra of CF 3 CCD, the isotopomer of this molecule in the ground, v 10 = 1 and v 10 = 2 states have been measured and studied by several authors [7–11]. …”

Internal dynamics in the molecular complex of CF3CN and H2O

“…The microwave spectrum, as well as millimeter-wave spectrum of the monomeric form CF 3 CN have been extensively studied due to its large dipole moment and large thermal population in the excited vibrational states 1,2,3,4,5,6,7,8,9,10,11,12,13 . The microwave spectrum, as well as millimeter-wave spectrum of the monomeric form CF 3 CN have been extensively studied due to its large dipole moment and large thermal population in the excited vibrational states 1,2,3,4,5,6,7,8,9,10,11,12,13 .…”

The microwave spectrum and structure of the argon trifluoroacetonitrile complex

“…The R in this case is a CF 3 group. The microwave spectrum, as well as millimeter-wave spectrum of the monomeric form CF 3 CN have been extensively studied due to its large dipole moment and large thermal population in the excited vibrational states [8][9][10][11][12][13][14][15][16][17][18][19][20]. This is the first spectroscopic work on argon trifluoroacetonitrile complex.…”
