Experimental and calculated electronic structure of gaseous CrO2F2 and CrO2Cl2

Abstract
The gas phase electronic absorption spectra of CrO2F2 and CrO2Cl2 have been measured in the visible, near ultraviolet regions. Interpretation has been made by comparison with a molecular orbital calculation for each molecule by the SCF-Xα-SW method. The calculated ground and excited states and observed electronic transitions correlate directly with those for the parent isoelectronic CrO2−4 and MnO−4 species.
