Spectral contrast angles
5-5
To illustrate the relationship between the spectral contrast angle and spectral
shape differences, consider the pairs of spectra shown in the next three
figures.
Spectra with different shapes
In the following figure, the absorbance spectra of two compounds, A and B, are
distinctly different. They therefore produce a large spectral contrast angle
(62.3
°
).
