Ground state bleach
WebDepopulation of the ground state (S 0) leads to a decreased absorbance (or increased transparency), which is due to the ground state bleach (GSB). Excited state absorption (ESA) gives rise to an increased absorbance, whereas stimulated emission (SE) gives rise to a decreased absorbance, just as does GSB. WebThe ground-state absorption is always subtracted as a reference, so any absorption of the ground-state sample contributes as negative ground-state bleach in the final signal. Probe...
