band shape

https://doi.org/10.1351/goldbook.08574
Description of the profile of a spectral band.
Note:
For a given band, the band shape is independent of the band height in Raman spectra, infrared absorption spectra and pATR spectra. The band shape changes if the band height changes in infrared transmission spectra or attenuated total reflection spectra.
