Charge dynamics in Porphyrins :
UV-Vis
Find the vibrational energy levels
Measure the response in longer wavelength to detect the triplet state
Redo UV-Vis for materials that had a tail in low wavelength due to suspension; sonicating for 30-60 minutes prior to measurements.
Finding all the papers that have done UV-Vis on porphyrines
TAS
Fluorescence (FL)
Q band scans
Qx(1,0) scan
Experiment ⚠(Challenge: at 589 nm, there are scattering contributions into the laser. Increasing the intensity makes it worst. Increasing the concentration may result in second order processes. )
