Numerical Y-Coordinate of Circular Dichroism Spectrum
In circular dichroism (CD) spectroscopy, the vertical axis represents either the absorbance or transmittance of light, determined by the ratio of the intensity of light passing through the sample to that passing through a reference material. This ratio is commonly referred to as "transmittance," denoted by "T," or "absorbance," denoted by "A," with absorbance often being the logarithmic form of the transmittance ratio.
Circular dichroism is an analytical technique that assesses the chemical composition and physical properties of a sample by measuring its differential absorption of left and right circularly polarized light across various wavelengths. The results are typically illustrated in a graph known as a CD spectrum.
The explanation provided is one possible interpretation of the vertical axis in a circular dichroism spectrum. The specific interpretation may vary depending on experimental settings and environmental conditions.
