Relations between aggregation state of thiacarbocyanine dyes in solutions and that adsorbed on silver bromide from there solutions

Absorption spectra of two thiacarbocyanine dyes in various solutions which had different aggregation ability of the dyes and reflectance spectra of the dyes adsorbed onto silver bromide grains from those solutions were taken. It could be concluded by comparison of these spectra that there was little or no correlation between state of aggregation of the dye in solution and that on AgBr grains when adsorbed from the solution
