Abstract
DURING experiments on pigment orientation in chloroplasts and grana, it was necessary to determine the directions in which linearly polarized light is preferably absorbed in a pigment molecule. This preference corresponds to the directions of maximum transition probability of the electronic transitions which give rise to the different absorption bands in the spectra. By studying dichroism and polarization of fluorescence for chlorophyll a, b, bacteriochlorophyll and the corresponding phæophytins, these directions have been investigated.
