Isolation and characterisation of the transient complex H3N ? Cl2 in the gas phase

The ground-state rotational spectra of the isotopomers H315⋯35Cl2, H315N ⋯37Cl35Cl, H315N ⋯35Cl37Cl, H314, N ⋯35Cl2 and H2DN ⋯35Cl2 of a transient complex of ammonia and chlorine have been observed by using a pulsed-nozle, FT imcrowave spectrometer incorporation a fast-mixing nozzle; the spectroscopic constants alliw the conclusion that the complex has C3v symmetry, with the nuclei in the order shown, and is of the outer type defined by Mulliken.
