Optical Constants of Water in the 200-nm to 200-microm Wavelength Region.
George M. Hale,Marvin R. Querry +1 more
TL;DR: Extinction coefficients k(lambda) for water at 25 degrees C were determined through a broad spectral region by manually smoothing a point by point graph of k( lambda) vs wavelength lambda that was plotted for data obtained from a review of the scientific literature on the optical constants of water.
