Natural Bond Order analysis, carbon

As an example of a spectrum obtained with a 10 m instrument (grating radius 10m) a recording of the carbon K emission line from the CO2 molecule is shown in Fig.5.7. As can be seen, the high resolution reveals a clear structure due to molecular vibration. Through careful analysis of a spectrum of this kind it is possible to evaluate the C-O bond length very accurately in the core-ionized molecule. It turns out that the bond length is shortened by about 2% when the Is core vacancy has been formed in the carbon atom. From the linewidth it is also possible to evaluate the natural lifetime of the C Is state (Sect.9.4.5). The lifetime is of the order 10" s. Atomic structure research using X-ray emission spectroscopy has been discussed in [5.9-13]. [Pg.72]
