Abstract:
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.
