Absorption or resonance Raman scattering are often used to identify and even quantify carotenoids in situ. We studied the absorption spectra, the Raman spectra and their resonance behavior of β-carotene in different molecular ...

Resonance Raman spectroscopy (RRS) is a promising technique for investigating samples with low concentrations of single constituents or many different constituents. The wavelength dependent resonance enhancement (resonance ...
