. This procedure allows one to judge about exciton localization on the single-geometry level. The studied H-type trans azobenzene tetramer is shown in Fig. . The H-type arrange-ment is motivated by azobenzene packing in self-assembled monolayers. The used model with intermolecular distance of 3.5 Å is an extension of the densely-packed dimer model used in our previous works. The ensemble of 100 MD snapshots demonstrating the extent of conformational disorder at ∼300 K is presented in Fig. .
