Researchers Measure Vibrationally Excited Water
At a minimum, predicting the absorption spectrum for water vapor requires a set of line positions and intensities and a shape function. Line intensities can be determined from a dipole moment surface, but a team of researchers from École Polytechnique Fédérale de Lausanne in Switzerland, University of Rochester in New York and University College London suggests in the Aug. 9 issue of Science that the best available surfaces are not accurate in the optical spectrum.
The researchers based their observations on a series of dipole moment measurements of water that had been highly excited...Read full article
