The rotational spectrum of acetone in its first torsional excited state (80 cm K1 above the ground state) has been identified and assigned. The vibrational levels of acetone are split into four torsional substates because of the interaction between overall rotation and the internal rotation motions

An investigation of the torsion-rotation-vibration energies in the ν 5 vibrational state in CH 3 CF 3 has been carried out using infrared and mm-wave spectroscopy. The lowest frequency parallel fundamental band ν 5 near 600 cm -1 has been measured at a resolution of 0.00125 cm -1 with Fourier transf
The millimeter/submillimeter transitions of the n 5 -2n 9 interacting bands of HNO 3 have been measured in the symmetric top limit. Torsional splittings in both vibrational bands have been observed. The 2n 9 splitting is due to the torsional motion of H around the NO whereas the n 5 splitting is due
