Comparison of the ν1 region of the qE-associated Raman spectrum (difference spectrum of light-treated-minus-dark recovery) induced by 528.7 nm excitation in Arabidopsis leaves from wild type and L17 treated with DTT. The ν1 region of the Raman spectra induced by 528.7 nm excitation of isolated zeaxanthin, violaxanthin, lutein, and neoxanthin dissolved in pyridine are also shown for comparison. rel., relative.
