Description

This work focuses on two Ru-bearing molecules: RuF and RuCl. Both molecules were created in a molecular beam apparatus at UNB. Their spectra were detected by laser-induced fluorescence. In the low-resolution survey of RuF from 400 to 770 nm , five bands were detected in the blue, green and infrared regions of the electromagnetic spectrum. Four of them were rotationally analyzed from high-resolution data. Three bands in the green region are associated with the ${}^4\mathrm{\Gamma }-X^4{\mathrm{\Phi }}_{4.5}$ system first observed by Steimle et al. (J. Chem. Phys. 124, 024309 (2006)). A new ${}^4{\mathrm{\Delta }}_{3.5}-X^4{\mathrm{\Phi }}_{4.5}$ transition in the blue region was also detected. The related molecule, RuCl was also created and spectroscopically detected for the first time. Two high-resolution bands of RuCl were rotationally analyzed, and the ground state was also found to be $X^4{\mathrm{\Phi }}_{4.5}$. The data provide detailed structural information about the molecules, such as bond lengths, vibrational frequencies, isotopic structure, spin-orbit interactions and hyperfine interactions.
