✦ Synopsis

Submillimeter wave rotational spectra of the vibrational states n 2 (A 1 ), n 3 (A 1 ), n 5 (E), and n 6 (E) in 12 CD 3 F and 13 CD 3 F have been recorded and assigned. The new data with previously published high resolution infrared spectra have been used to determine the excited state rotational parameters. The upper states of the four fundamentals in each isotopic species were treated simultaneously due to strong vibration-rotation interactions. Both ground state combination difference data from the previously published infrared transitions and ground state rotational transitions have been used to determine accurate ground state rotational parameters including the rotational constant A 0 and the centrifugal distortion constant D K 0 . The number of observed rotational transitions in the vibrationally excited states is 131 for 12 CD 3 F and 109 for 13 CD 3 F, respectively.
