Infrared Intensities of Liquids XIV: Accurate Optical Constants and Molar Absorption Coefficients Between 4800 and 450 cm-1 of Chlorobenzene at 25°C from ... Accurate infrared absorption intensities of liquid chlorobenzene at 25°C are presented. Their accuracy was estimated from the agreement betwee...
integral reflectance, transmittance and the resulting absorption of intact and descaled butterfly wings of the black-winged Pachliopta aristolochiae (Papilionidae), the white-winged Pieris brassicae (Pieridae), and the yellow-winged Gonepteryx rhamni (Pieridae) were determined between 350 and 800 nm...
Regression analysis revealed a strong relationship between the SPAD estimate and leaf transmittance and absorptance. The reflectance relationship, although still present, was not as accurate. The study indicates that the SPAD meter could be used to provide a rapid estimate of leaf absorbance and ...
Samples were collected on filters, which were used for the determination of Absorption Angstrom Exponent (AAE). In addition, the content and composition of elemental carbon (EC) and organic carbon (OC) were determined, and the interrelationships between these and the AAE were examined. It was ...
