Gas-Phase Complexes: Possible Prereactive Gateways for Reactions of Halogens with NH3, H2O, and H2S
Graphical Abstract
Molecular beams with the carrier gas argon contain prereactive complexes of halogens and interhalogens with NH3, H2O, and H2S, as detected by Fourier-transform microwave spectroscopy; the structures have been elucidated. The partial structures of NH3, H2O, and H2S as well as F2, ClF (cf. picture), Cl2, BrCl, and Br2 are almost the same for the complexes as for the free molecules. The weak complex bonds result from electrostatic forces.
