In vivo determination of carotenoid resonance excitation profiles of Chlorella vulgaris, Haematococcus pluvialis, and Porphyridium purpureum
Under stress, certain species of algae produce pigments such as astaxanthin, β-carotene, or phycoerythrin for protection against photosynthethic stress. These pigments are of high commercial demand,Expand
Resonanz-Ramanspektroskopie an Carotinoiden in Algen zur Bestimmung der Kinetik des Violaxanthinzyklus
This thesis describes the first in vivo approach to directly measure the kinetics of the violaxanthin cycle using resonance Raman spectroscopy. The violaxanthin cycle is a regulation mechanism withinExpand
Excited state characterization of carbonyl containing carotenoids: a comparison between single and multireference descriptions.
Among the investigated functionals, the meta-GGA (and in particular M11L and MN12L) functionals show to perform the best for all six investigated systems, and the DFT/MRCI results are used to benchmark single-reference time-dependent DFT-based methods. Expand
Qualitative and quantitative FT-raman analysis of plants
Raman spectroscopy has been found to be a reliable and non-destructive method for rapid discrimination of different plant species or chemotypes if characteristic key bands can be observed in theExpand
Recent Advances in Raman Analysis of Plants: Alkaloids, Carotenoids, and Polyacetylenes
This paper demonstrates the special potential of Raman spectroscopy for the study of selected plant metabolites. Carotenoids, which are beneficial components in fruits and vegetables, have been shownExpand
Applications of Raman and Surface-Enhanced Raman Scattering to the Analysis of Eukaryotic Samples
In this chapter, we discuss Raman scattering and surface-enhanced Raman scattering (SERS) for the analysis of cellular samples of plant and animal origin which are several tens to hundreds of micronsExpand
Semiempirical and Raman spectroscopic studies of carotenoids.
Semiempirical AM1 calculations have been carried out for beta-carotene and the three xanthophylls containing oxygen functions and indicate that substitutions on the terminal rings have a minimal effect on the conformation of the chromophore. Expand

This chapter discusses the basic principles of RR and IRD methods and some of their important applications, and the main advantage of IRD is its capability to detect protein molecular changes. Expand
Vibrational spectra and Raman excitation profiles of some Schiff bases
Abstract The pre-resonance Raman spectra of three Schiff bases have been recorded and analysed. The theoretical Raman intensity factors have been calculated using Albrecht and Hutley's theory forExpand
The Electronic Spectroscopy of Photoreceptors (Other Than Rhodopsin)
A number of organisms ranging from prokaryotic bacteria to eukaryotic mammals directly respond to light of different wavelengths in terms of various photobiological reactions. A photobiologicalExpand
