Remarks on relations between X-ray emission and auger transition rates and molecular properties: chemical effect

Relations are pointed out that there exist between (1) the X-ray emission rate and the π bond order and (2) the Auger transition rate and the valence electron density (chemical effects) resulting from C ls vacancy in carbon-containing molecules. Recognition of these relations is very important for analysis of experimental data and for prediction of these quantities, for which no data are available. (author)
