What are Absorption, Excitation and Emission Spectra?

In this blog post, the differences between molecular absorption, excitation and emission spectra are explained.Absorption SpectraAbsorption spectra (also known as UV-Vis spectra, absorbance spectra and electronic spectra) show the change in absorbance of a sample as a function of the wavelength of incident light (Figure 1), and are measured using a spectrophotometer. Absorption spectra are ...
