Of the processes that reduce the intensity of X‐rays passing through matter, photoelectric absorption, scattering and extinction are important for the X‐ray wavelengths used in crystallography. This chapter discusses each in turn. Different kinds of absorption corrections are described and parameters for use in calculating absorption corrections are tabulated.


  • absorption;
  • absorption corrections;
  • attenuation coefficients;
  • dispersion;
  • extinction;
  • mass absorption coefficients;
  • photoelectric absorption;
  • transmission coefficients;
  • X‐ray absorption
