From: Non-radiative relaxation of photoexcited chlorophylls: theoretical and experimental study
Transient absorption of ChlA (solid black curve) and ChlB (dashed red curve) dissolved in ethanol, probed in the Qy region after excitation at 442 nm.
(a) Typical transient absorption spectra recorded at delay time of 1 ps. (b) Typical transients recorded at 672 nm and 652 nm for ChlA and ChlB, respectively. The samples were diluted to OD ~ 0.8 at the pump wavelength. The signals corresponding to ChlB are multiplied by two.
