Popis:	Complementary tri-stimulus spectrophotometry appears as an interesting method for investigation of metal complex equilibria in solution. This has been demonstrated on various examples including bivalent (copper, vanadyl) or trivalent (iron, aluminum, yttrium, lanthanum) metal ions coordinated by several organic ligands.The formation, pH range of existence, and the number of absorbing species in colored solutions of binary or ternary (particularly bimetallic) systems are easily determined by calculation of the complementary tri-stimulus co-ordinates.The advantages (and disadvantages) of the technique are discussed. This qualitative method appears to be very useful for a first approach of coordination phenomena but needs to be completed by quantitative studies using classical methods.
