## spectral bandwidth error

in spectrochemical analysis
https://doi.org/10.1351/goldbook.S05812
To measure the true shape, particularly the true maximum of an absorption band, the spectral bandwidth $$\Delta \lambda$$ of the instrument must be much less than the width of the absorption band. A spectral bandwidth error results from using too large a bandwidth relative to the absorption band being measured.
