Van der Waals clusters involving mercury have been studied in a supersonic expansion beam crossed with a laser. The expansion beam consisted of Argon gas seeded with Hg vapor from a heated reservoir. HgmArn and Hgm (m,n ≥ 1) clusters were produced in the beam by collisional mechanisms. In this thesis, previously unobserved fluorescence spectra were observed for several different laser excitation wavelengths. Five of these wavelengths, 2534.3 A, 2534.6 A, 2535.8 A, 2536.0 A and 2537.2 A corresponded to clearly defined absorption wavelengths in the excitation spectrum. The sixth wavelength at 2533.7 A corresponded to a plateau in the excitation spectrum. None of these fluorescence spectra can be assigned to definite transitions at this moment, although three of them are probably due to Hg2Ar and correspond to transitions from various vibrational states of an excited electronic excited state to various vibrational levels of the ground electronic state. One fluorescence spectrum is probably due to Hg3, but the remaining two fluorescence spectra clearly require further study.Dept. of Physics.
