The final limiting stage of structural simplification of photochromic Schiff base was reached by the following statement: two molecules, salicyli­dene methylamine and its butyl analogue, show transient absorption bands (at room temperature) peaking at ≈ 22000 cm^{-1}. These bands are charac­teristic of the phenomenon of photochromism. They are similar to the corre­sponding spectra detected earlier for several larger, symmetric systems be­longing to the same family. Experimental characterization of both molecules was compared with the theoretical calculations: geometry optimization and transition energies, performed for enol, keto, and the photochromic form of salicylidene methylamine.
