Figure 4. Qualitative predictions from the point-dipole expression (Equation 3) for spectral shifting of dimers. Dimer formation splits the excited state into two levels, one which allows transition to the ground state, and one which is silent for the case of parallel molecules in the dimer. The spectral shift depends on the stacking angle of the pair of molecules. The slipped structure is the precursor of the red shifted 1-aggregate, a desirable structure for photographic sensitization.

Figure 5. Slick" molecules in the possible modes of interaction during an optical transition, with transition density represented by vertical displacement from the horizontal sticks. Right, the transition densities cancel each other and are silent, and left, the transition densities add so that the dimer becomes a supermolecule with a single allowed optical transition having the combined dipole strength of the two participating molecules.

Figure 8. Wavelength vs. absorptance for a normal photographic coating of a thiacarbocyanine dye on cubic crystals (a), and on octahedral crystals of AgBr / (2.5% I) (b). The rising absorption to the left of each plot is the intrinsic absorption of the silver halide. (Reproduced, with permission, from Ref. 35.

Figure 10a. Results of coating matching octahedral AgBr I (1% I) emulsions on clear acetate film base and measuring %R, % T. On incubation at 38°C, the red-shifted aggregates are simply ordered increasingly with time, and a modest red shift occurs. The central ethyl group prevents formation of the 60° structure.

The circles represent surface positions tor Ag ions. In the absence of the dye, half of the Ag positions are filled randomly. When an attractive ligand interaction is established between the heterocyclic sulfurs of the dye and two Ag ions, position, A,A are filled, and B,B must be emptied to remove a repulsive interaction between the 7,7 protons of the dye and the Ag ions. Positions C,C will he emptied to maintain local electrical near-neutrality if the dye is a cationic carhocyanine. If a charge-compensated betaine dye (e.g. monosulfopropyl) is added, one of the C.C positions may be filled, or if an anionic dye (Fl.ti -disulfopropyl) is added, both may he filled.
