Abstract

This dataset reports the Ultraviolet visible optical extinction coefficients for multiple atmospherically-relevant compounds. Following Beer's law  (A = e*l*C, where A is absorbance, e is the extinction coefficient, l is the pathlength of the optical measurement, and C is the concentration of the compound in solution), we report "e" in units of M-1 cm-1. The data were taken in pure water. Spectra for organic acids are reported at two pH (2 and 5).

Methods

The data were taken with a UV-Vis spectrophotometer. Extinction coefficients are calculated based on the measured absorbances, pathlength, and the known concentrations of the solution.
