The knowledge of the vibrational properties is of key importance to understand their function of β‐carotene molecules in the reaction centre of the light‐harvesting complexes. We present polarisation‐dependent Raman spectroscopy on β‐carotene molecules in two different environments: first single dimeric photosystem II crystal, and second encapsulated β‐carotene in single‐wall carbon nanotube bundles. Both systems have nearly perpendicular or parallel orientated β‐carotene molecules. We compare the dependence of their Raman spectra on the polarisation of incident and scattered light.
