| dc.description.abstract | In the first part of this thesis, three ruthenium-bearing diatomic molecules have been studied in the visible region of the electromagnetic spectrum. Ruthenium monofluoride, ruthenium monochloride and ruthenium monoxide molecules were created in a molecular beam apparatus. The high-and low-resolution spectra of these small molecules were taken with the laser-induced fluorescence technique. The dispersed fluorescence technique was used to determine the vibrational frequencies of the RuF, RuCl and RuO molecules. The results of the high-resolution analysis of the spectra revealed extensive isotopic structures of the three molecules. Spin-orbit and hyperfine interactions in the ruthenium monofluoride molecule were observed and analyzed. Hyperfine structure in the ruthenium monoxide molecule was also detected and studied. In the second part of the thesis, three medium-sized ring molecules, catechol, furan and pyrrole, belonging to the C2v point group, have been studied in the infrared region. Vibrational bands of pyrrole and furan were collected between 800-900 cm-1 at the Canadian Light Source with an FTIR technique. Observed vibrational bands of pyrrole and furan in that region were studied. A nearby level that had A2 symmetry which could not be accessed from the ground states had perturbed the fully overlapped bands of these molecules. Also, progress has been made in obtaining the first high-resolution rotationally resolved vibrational band of catechol at the Canadian Light Source. | |
