    • In comparison to the case for irradiation of NMR samples in glass tubes, the concentrations for UV-vis samples are much lower and quartz cuvettes were used. This resulted in much shorter irradiation times.

    • note
    • There is another distinction between visible and UV irradiation of this system. Visible irradiation can completely convert 3a to 4a, since 4a does not absorb at long wavelengths and cannot be converted to 3a by visible irradiation. On the other hand, UV irradiation does not completely convert 4a to 3a, since the Sa that is formed also absorbs UV light and converts back to 4a until a steady-state mixture of 3a and 4a is obtained. Therefore, the inner-filter effect of 3a makes conversion of 4a to 3a more inefficient as the steady state is reached. In any event, the loss of isosbestic point is not due to extended UV irradiation, since the isosbestic point is lost when UV irradiation commences.
