Investigation of core-excited quantum yield spectra of high-symmetric boron compounds

Abstract

The quantum yield spectra of several boron compounds with tetrahedral and trigonal surroundings have been measured in the region of the BK edge using synchrotron radiation. The core-excited states of the fluorine compounds are discussed on the basis of Xα- SW calculations of BF 3, CF 4 and BF − 4-systems. From the correlation between local symmetry and fine structure of the spectra information is derived on the structure of boron—oxygen compounds.
