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. )
