- The time for the porphyrin film to change from green to pink was recorded. (took
- The film was sliced to have the width of the UV-Vis cuvette.
- The thickness of the film was measured.
- The sliced film was placed in the cuvette and a UV-Vis spectra was taken.
- The sliced film was then placed into additional 2% wt H2SO4 until it turned green. (Time to turn green =
