| Abstract: | The bending vibration-rotation band ν4 of DCCF was studied. The measurements were carried out with a Fourier spectrometer at a resolution of about 0.03 cm?1. The constants B0=0.29141(1)cm?1, α4=?5.02(2)×10?4cm?1, q4=4.52(3)×10?4cm?1, and D0=9.2(4)×10?8cm?1 were derived. The rotational analysis of the “hot” bands 2ν4(Δ) ← ν4(II) and 2ν4(Σ+) ← ν4(II) was performed. In addition, the “hot” bands ν4 + ν5 ← ν5 were assigned. A set of vibrational constants involved was derived. |
