Abstract

Triplet-state dynamics in Chl-a/Per mixtures in organic solvent and in native H-PCP were studied by means of step-scan FTIR spectroscopy. A single decay component of 10 μs was observed for the H-PCP triplet, the spectrum of which closely matches the 13 μs component of A-PCP [Alexandre et al., Biophysical Journal 93 (2007) 2118-2128], implying that in H-PCP, as in A-PCP, the peridinin triplet state is shared with Chl-a. In a mixture of Chl-a and Per in THF, TEET from
