If we take into consideration all of the available data we come to the model 

 reproduced in Fig. 9. This model does not reproduce all the details of the

electron density distribution in the lipid layer. It must, however, be noted 

 that the preparation used here has also undergone secondary changes to a 

 certain extent, and that the scattering curve analysis was in no case possible 

 without hypotheses. The model has chlorophyll in two different types of asso- 

 ciation that could correspond to the 670 and 683 mu forms of chlorophyll a 

 in vivo. Only one form is in the neighborhood of protein. In both layers it is 

 possible to have individual chlorophyll molecules as well as their polymers.
