Abstract
The Raman spectrum of Cs2O2 excited at 632.8 nm shows a single O-2(-2) fundamental band at wavenumber of 742.5 cm(-1) and second and third overtones at 1468.5 and 2176.8 cm-1, respectively. The harmonic wavenumber omega(e) = 759.5 +/- 0.7 cm(-1) and anharmonicity constant omega(e)x(e) = 8.4 +/- 0.3 cm(-1) were calculated directly from the measurements. These results are compared with omega(e) = 1151.0 +/- 1.5 cm(-1) and omega(e)x(e) = 9.6 +/- 0.5 cm(-1) recently found for O-2(-) ion in CsO2 by others. The lower omega(e)x(e) of O-2(-2) relative to that of O-2(-) indicates a broader (smaller curvature) anharmonic oscillator potential well. Copyright (C) 2002 John Wiley Sons, Ltd.
