“…Raman scattering measurements under resonant conditions enhance the Raman modes which are coupled to the electronic transition in a process known as resonance Raman scattering (RRS). 29 In our case, the surface-enhanced resonance Raman scattering (SERRS) spectra at the gold and silver interfaces become identical, thus indicating that the vibrational modes coupled most strongly to the electronic transitions along the conjugated backbone of MEH-PPV are nearly identical in the presence of silver and gold, providing further evidence that the differences discussed above are not due to large conformational changes of the conjugated polymer.…”

“…Both reflectance and resonance Raman spectroscopy have already been applied for this task. 2,7 While reflectance spectroscopy makes use of the absorption spectrum, i.e. the electronic transitions and their fine structure, to identify and analyze molecules, Raman spectroscopy utilizes the vibrational fingerprint of a molecule.…”

Absorption and resonance Raman characteristics of β-carotene in water-ethanol mixtures, emulsion and hydrogel

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 environments set up as mixtures from lipid (emulsion) and non-polar (ethanol) solvents and a polar component (water) with regard to their application as references for in situ measurement. We show how both absorption profiles and resonance spectra of β-carotene strongly depend on the molecular environment. Most notably, our data suggests that the characteristic bathochromic absorption peak of J-aggregates does not contribute to carotenoid resonance conditions, and show how the Raman shift of the C=C stretching mode is dependent on both, the molecular environment and the excitation wavelength. Overall, the spectroscopic data collected here is highly relevant for the interpretation of in situ spectroscopic data in terms of carotenoid identification and quantification by resonance Raman spectroscopy as well as the preparation of reference samples. In particular, our data promotes careful consideration of appropriate molecular environment for reference samples.

“…In fact, the resonance efect can increase the scatering cross section to exceed any of-resonance Raman scater and, importantly, even rival intrinsic luorescence from the species. RRS thus has profound analytical potential and has been comprehensively reviewed elsewhere for the general life science ield [7] and speciically for applications in photosynthesis [8]. Here, its role in the assessment of carotenoids is examined explicitly.…”

Raman spectroscopy provides detailed information about the molecular structure of carotenoids. Advances in detector sensitivity and acquisition speed have driven the expansion of Raman spectroscopy from a bulk analytical tool to a powerful method for mapping carotenoid abundance in cells and tissues. In many applications, the technique is compatible with living organisms, providing highly speciic molecular structure information in intact cells and tissues with subcellular spatial resolution. This leads to spatial-temporalchemical resolution critical to understanding the complex processes in the life cycle of carotenoids and other biomolecules.
