| The absorbance was measured with a microtiter plate reader at a test wavelength of 405 nm. |
| Under visible light irradiation, much longer durations were necessary to achieve similar absorbance decreases. |
| The 10 ml samples were centrifuged and the absorbance of the supernatant was measured at 280 nm to determine the lignin content. |
| The total cavity loss is then the sum of the mirror transmission and the sample absorbance. |
| This absorbance is an average for healthy leaves as measured with an integrating sphere. |
| Upon measuring the absorbance of a labeled peptide at a given angle of incidence, two different dichroic ratios were obtained. |
