Internal Methyl Rotation and Molecular Structure of Trifluorotoluenes: Microwave Rotational Spectra of 2,3,4- and 2,4,5-trifluorotoluene

The microwave rotational spectra of 2,3,4- and 2,4,5-trifluorotoluenes, along with all 13C isotopic species in natural abundance, have been recorded in the frequency range 8-27 GHz employing pulsed...
