The Millimeter-Wave Rotational Spectrum of CF3CN in Excited Vibrational States

The millimeter-wave rotational spectrum of CF3CN in the excited vibrational state v8=2

“…Again in this state, as with v 7 = 1 and v 8 = 1 states [12], it was assumed the quadrupole splitting is the same as in ground state. This enabled us to assign lines with high k values such as (k À ') ' = À16 À2 , À17 À2 in J = 16, À17 À2 , À18 À2 in J 00 = 18, À13 À2 , À14 À2 in J 00 = 19 and À15 À2 , À17 À2 in J = 20.…”

“…For producing the initial prediction list, the parameters from the v 8 = 1 state [4,12] such as A, B, D J , D Jk , and q þ t were used, extrapolated as was done before for CF 3 CCH [9].…”

“…The experimental conditions were the same as those established for the study of the first excited states v 7 = 1, v 8 = 1, and v 4 = 1 [12]. Considering the variation of population of energy states in accordance with the Boltzmann factor, the energy of the vibrational state v 8 = 2 determines an absorption intensity of rotational spectrum which is only 6% of that of the ground state at 195 K [1].…”

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.…”

“…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 .…”
