Linear dichroismus
Nettetsmall unless the intensities of linear dichroism and linear birefringence are 100 times larger than that of the circular dichroism. The term of 1/2(LD’LB – LDLB’) is contained in m 03 and m 30 of Equation (1). Since the units of LD, LD’, LB and LB’ in Equation (2) are radian, the values of LD, LD’, LB and LB’ are smaller than NettetLinear dichroism (LD) of the carotenoid, rhodopin glucoside, and the 800 and 850 nm absorbing bacteriochlorophylls in the LH2 antenna complex from membranes of Rhodopseudomonas acidophila strain 10050 squeezed in polyacrylamide gels is reported. A model is presented for computing the ratio of the LD-to-isotropic absorption …
