The near infrared, visible, and near ultraviolet overtone spectrum of water
MetadataShow full item record
New long path length, high resolution, Fourier transform spectrometer measurements for water are presented. These spectra cover the near infrared, visible, and near ultraviolet regions and contain water transitions belonging to all polyads from 3v to 8v. Transitions in the range 13 100-21 400 cm-1 are analyzed using line lists computed using variational first-principles calculations. 2286 new transitions are assigned to H2 16O. These result in the observation of transitions in 15 new overtone and combination bands of water. Energy levels for these and other newly observed levels are presented. It is suggested that local mode rather than normal mode vibrational assignments are more appropriate for the vibrational states of water in polyads 4v and above.
