On the problem of obtaining accurate circular dichroism. Calibration of circular dichroism spectrometers

Artikel i vetenskaplig tidskrift, 1976

It is questioned whether common circular dichroism (CD) spectrometers can be relied upon if they are calibrated at a single wavelength only. A procedure for obtaining the influence of certain instrumental parameters is described, and relations are given to correct the CD. This discussion was found relevant on examination of a particular commercial CD spectrometer for which fairly large corrections were necessary. It is suggested that the different values reported for two common CD standards may be explained by errors of the type considered, in different instruments.
