Powder dictionary (pdCIF) version 1.0.1
Code identifying the wavelength appropriate for this peak from the wavelengths in the _diffrn_radiation_ list. (See _diffrn_radiation_wavelength_id.) Most commonly used to distinguish K\a~1~ peaks from K\a~2~ or to designate where K\a~1~ and K\a~2~ peaks cannot be resolved. For complex peak tables with multiple superimposed peaks, specify wavelengths in the reflection table using _pd_refln_wavelength_id rather than identifying peaks by wavelength.
