Abstract
The optical-absorption spectrum of has been observed by depletion spectroscopy in the 400–700-nm range. The experimetnal results are compared with theoretical spectra calculated for the three structures in competition and we have been able to unambiguously determine the most stable geometry as being the tripyramidal geometry.
