educt การใช้

Generally, a specific functional group of the compound participates in the derivatization reaction and transforms the educt.
Often the homogeneous absorption spectrum of the product is much different from that of the educt, so that the corresponding inhomogeneous bands do not overlap.
If such a photochemically active molecule absorbs light, then with a probability of a few percent it will not return to the initial, educt state, but will rather switch over to a new, product ground state.
