Laser-induced fluorescence and dispersed fluorescence spectroscopy, isotopic studies, and lifetime measurements for rhodium monoxide

摘要

Rho molecules have been generated from laser-ablated rhodium atoms and O-16(2) or O-18(2) and studied spectroscopically. Thirty LIF band features in the 500-650 nm region have been examined. Dispersed fluorescence and excited state lifetime data have been recorded. Measurements on vibrational levels upsilon = 0 to 5 of the molecular ground state give omega(e) = 807 cm(-1) and (omega(e)x(e) = 5 cm(-1). Excited state vibrational parameters have been estimated. Evidence is found for low-lying electronic states at 3744, 5980 and 6477 cm(-1). (C) 2003 Elsevier Science B.V. All rights reserved. [References: 5]
