The rotational spectra of six isotopologues (CF 3 35 Cl⋅⋅⋅ 14 NH 3 , CF 3 37 Cl⋅⋅⋅ 14 NH 3 , CF 3 35 Cl⋅⋅⋅ 15 NH 3 , CF 3 37 Cl⋅⋅⋅ 15 NH 3 , CF 3 35 Cl⋅⋅⋅ 14 ND 3 and CF 3 37 Cl⋅⋅⋅ 14 ND 3 ) of the CF 3 Cl⋅⋅⋅NH 3 adduct have been investigated and analyzed by pulsed jet Fourier transform microwave spectroscopy. Rotational, centrifugal distortion and quadrupole ( 35 Cl, 37 Cl, 14 N) coupling constants have been precisely obtained. The two subunits of the complex are held together via a Cl⋅⋅⋅N halogen bond interaction. Information on the internal dynamics and on the dissociation energy of the complex is provided.
