摘要：Gas-phase refractory molecules are ideal venues for testing Fundamental Physics and investigating relativistic effects. They also can be used as remote probes of the physical conditions of stellar atmospheres and other energetic environments. The requisite molecular properties for their utilization in these roles are best derived from an analysis of high resolution electronic spectra. Three examples from our recent studies will be highlighted. A sensitive two-dimensional (2D) spectroscopic approach for detection of new molecules will be described.
(a) Characterization of the state of 181TaN via electronic spectroscopy
(b) Optical Zeeman spectroscopy of VO and TiO
(c) Bonding in gold containing molecules
