Note that there is not a hint of purple color in the sample after the reaction.

Fluorescence W samples

  1. Fluorescence measurements
    1. 290 nm excitation, 10.0 nm slit width
    2. Emission: 310-540 nm, 10 nm slit width
    3. 100 nm/min
    4. 1 scan every 3 minutes

Note: the second to last scan didn't save properly.
