  1. The λi and αi represent the wavelength position and absorption coefficient at corresponding absorption A1 or A2 maximum for the external (E) and central (C) parts and displayed ratios A1:αC/αE and A2:αC/αE represent the concentration change between external and central part. Spectral distance (∆λ) is then defined as a spectral shift between measured absorption (λA1) and emission (λE) maxima.
