 Title: Microwave spectroscopy and structure determination of H2S − MI (M=Cu,Ag,Au) Author(s): Medcraft, Chris Contributor(s): Walker, Nick; Legon, Anthony Subject(s): Chirped pulse Abstract: A series of hydrogen sulphide-metal iodide complexes (\chem{H_2S}-MI, M$=$Cu, Ag and Au) have been measured via chirped pulse Fourier transform microwave spectroscopy between 7.5-18 GHz. The complexes were generated in a supersonic expansion via laser ablation of the metal and decomposition of CF$_3$I. Experimental structures were obtained by least squares fitting of structural parameters to the rotational constants of deuterium and metal ($^{63}$Cu / $^{65}$Cu and $^{107}$Ag / $^{109}$Ag) isotopologues. Interestingly K$_{-1}$=1 transitions were observed in the spectra containing D$_2$S, these were not observed in previous studies of similar molecules (H$_2$S-MCl). This allowed for the determination of an extra rotational constant and, consequently, extra structural information could be obtained. The structures are compared to high level coupled cluster theory calculations.
