We reinvestigated the self-aggregation of 1-cyclohexyluracil (1CHU) in solutions. Wavelength dependent absolute extinction coefficients of the monomer and of dimers are presented on the basis of a simple deconvolution method. Two isomeric dimer structures coexist in a solution with similar abundance. Our results are supported by RI-B3LYP/TZVP calculations within the conductorlike screening model framework to account for solvent effects in the ab initio calculations.
