High Resolution Spectroscopy of Ruthenium Monoboride and Iron Monohydride molecules

''L'équipe Spectrométrie Moléculaire invite Allan Adam de l'Université de New Brunswick.
Abstract: Many diverse fields, including astrophysics, chemical catalysis, surface chemistry, and the semiconductor industry rely on detailed information about the geometrical structure, bonding, and electronic configurations of molecules and solids. Optical spectroscopy continues to be one of the most effective probes of these properties. Our research work with the UNB laser spectroscopy group specializes in high-resolution laser-based spectroscopy of diatomic transition metal-containing molecules and small metal-containing polyatomics, the results of which are either directly applicable to the fields mentioned above, or are very useful prototypes that illuminate the workings of more complex systems. In this talk, I will be describing how we generate these highly-reactive metal-bearing radicals using the laser ablation process (and most recently an electric discharge process) and how we achieve well-resolved simplified spectra where fine and hyperfine effects can be measured. The two examples that will be discussed in the talk will be recent results from electronic spectra of the ruthenium monoboride molecule and the iron monohydride molecule.''
