Reyes-Pérez, S. Le Calvé, P. Mirabel Title: Near-UV molar absorptivities of alachlor, mecroprop-p, pendimethalin, propanil and trifluralin in methanol Journal/Source: J. Photochem. Photobiol. A: Chem., 193, 237-244, (2008); doi:10.1016/j.jphotochem.2007.07.001 Data: diagram, table Energy/Wavelength range: 240 - 300 nm Resolution: 2 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (methanol) pH: Comments: The absolute values of molar absorptivity coefficients at 253.7 nm were determined according to the Beer-Lambert law :  epsilon = 381 ± 28 for alachlor,  epsilon = 11240 ± 1030 for pendimethalin,  epsilon = 22220 ± 1850 for propanil and  epsilon = 5720 ± 410 for trifluralin (in units of M-1 cm-1).
