Experimental fluorescence spectrum from a selenomethionine protein measured at the Se K-edge. Inset: the anomalous scattering factors ( and ) are calculated from the experimental fluorescence data using the program CHOOCH. The value of at the peak (12664.70 eV) and the inflection (12662.46 eV) energies are −7.23 e and −10.35 e, respectively; while for the respective values are 6.58 e and 3.49 e. |
