Under visible light irradiation, much longer durations were necessary to achieve similar absorbance decreases. |
The total cavity loss is then the sum of the mirror transmission and the sample absorbance. |
The term extinction coefficients describes the absorbance spectra of a single pure substance at known concentrations. |
The 10 ml samples were centrifuged and the absorbance of the supernatant was measured at 280 nm to determine the lignin content. |
First, the emission spectrum of the donor molecule must overlap with the absorbance spectrum of the acceptor. |
This absorbance is an average for healthy leaves as measured with an integrating sphere. |
