Wavelength-dependent asymmetry

Here gx is the wavelength-dependent asymmetry parameter (see Equation (36) below). 

According to the above rule, for instance, one has to select Xq = 228 nm for compound 20 (Table 2) and also = 228 nm for 24 (Table 2). The description of the ORD of the atomic asymmetry term is more complicated. Each of the three terms (representing the ORD of the three asymmetric carbon atoms (k) (k = 1, 2, 3) of I) may exhibit a different wavelength dependence according to equation 19. ... 

We recently carried out a systematic invest ation of the influence of chemical bonding on the positions and the profiles of the emission lines of the 3d transition elements. All these elements exhibited a definite dependence of the x-ray wavelength on their valence and on the electronegativity of the neighborii atoms. The width and the asymmetry of the lines depended on the number of unpaired electrons and this was also true of the magnetic moments of simple compoimds. These results enabled us to obtain much information on chemical bondii, particularly in the case of complex compounds.
