Popis:	in this work dynamics of chromone compound photo-induced transformation is investigated using ultrafast pump-probe measurements. Relaxation dynamics of transient absorption spectrum is described by two time constants of 1.5 ps and about 1.5 ns. Energy diagram of chromone photoinduced transformation dynamics is suggested.
