Circular dichroism (CD), defined as the difference in absorption between left and right circularly polarized light, is used to spectroscopically study the structures of chiral materials. In this article, various methodologies are presented for characterizing the performance of CD spectrometers to determine (1) experimental conditions for optimal data(More)
Both the voltage-induced and the inherent (static) birefringence of a photoelastic modulator (PEM) affect the phase difference between orthogonal components of light passing through the PEM. This phase difference determines the polarization state of the light and is essential for determining true circular and linear dichroism (CD and LD, respectively)(More)
Nearly all circular dichroism (CD) and linear dichroism (LD) spectrometers use a photoelastic modulator (PEM) in which an optical element is stressed using a high-tension voltage (HT) signal to induce birefringence. The birefringence consequently produces a phase difference between perpendicular polarization states of light passing through the PEM that is(More)
