We discuss the influence of absorption flattening (AF) on CD spectra, aiming at finding a simple way to compensate the induced distortions. A simple algebraic formalism is proposed based on an unconventional measuring approach, which makes use of a commercial unit. Validation of the proposed compensation method for AF is conducted not only on the already studied CD Vis spectral region of a Co chiral complex with the use of an AF emulator, but also on the far UV CD spectra of poly‐ L ‐glutamic acid suspensions with different turbidity levels. Comparison with some correction factors proposed in the literature is presented. Chirality, 2008. © 2008 Wiley‐Liss, Inc.
