The microwave spectrum of 2,2,2,-trifluoroethylamine has been studied to investigate the possibility of intramolecular hydrogen bonding between the amino potons and the fluorine atoms. The ground state has been assigned for the parent isomer ($CF3CH2$ $NH2$) and two isotpes ($CF3CH2$ NHD and $CF3$ $CH2$ $ND2$). For $CF3CH2NH$ the dipole moment components have been determined and excited torsional state lines have been measured. Two staggered rotational isomers are possible for rotation about the C-N bond axis. Of these two, only the form which is more conducive to hydrogen bonding is observed.
