title: Visible and near-ultraviolet absorption spectrum of liquid water.
abstract: The optical absorption of pure liquid water in the 300-700-nm region has been measured by use of a long (1.5-m) path-length cell. The absorption spectrum coincides well with the edge of previous data in the 200-320-nm region and provides reliable data in the 320-420-nm region that has until now been a region of considerable unreliability. The data obtained for the 420-700-nm region agree quite well with the means of the existing literature in that well-studied region. The absorptions in the 550-700-nm region show evidence for the overtones and combination tones of the well-known OH stretching frequency at 3500 cm(-1).
