Abstract	Using data on the stability of complex forms, electron absorption spectra of copper (I)-, silver (I)-, and gold (I)—thiourea complexes in an aqueous solution M$_{i}$tu$_{j}$ (Ag: i=1, 2, j=1–3; Cu: j=1, 2; Au: j=2) are calculated from the spectra of solutions of a known analytical composition. Parameters of particular bands of the absorption spectra of these complexes are given. It is found that the integral intensity of the spectra of the solutions is proportional to the concentration of thiourea in the solution with high accuracy. The same is also valid for the spectra in solutions that contain mercury (II) and thiourea. The total intensity of longwave bands in the spectra of the complexes is proportional to the number of ligands in a molecule of the complex.
