Comments |
Fitting the NLA
curve displayed in Fig. 3 yields a ground-state absorption
cross section of 1.3(±0.2)
10^-15 cm2 at 680 nm for
LHC-II (and 1.5(±0.2)
10^-15 cm2 for excited state absorption). This value is about four times that of monomeric
Chl a in diethyl-ether solution (3.1
10^-16 cm2 at peak
wavelength, compare Shipman, 1977 Oscillator and dipole strengths for chlorophyll and
related molecules. Photochem. Photobiol. 26: 287–292.). |
