integration range

of a spectrum
https://doi.org/10.1351/goldbook.08259
Frequency or wavenumber range over which the integrated intensity of an absorption band is measured by numerical integration of the area under the band.
Notes:
  1. For Gaussian bands, integration over one full width half maximum to each side of the band centre yields 98 % of the area under the band.
  2. Lorentzian bands integration over 3.1 or 15.9 full width half maximum to each side yields 90 % and 98 % of the band area.
