Spectral resolution: Measurement, Doppler effect & IUPAC definition

The spectral resolution of a spectrograph, or, more generally, of a frequency spectrum, is a measure of its ability to resolve features in the electromagnetic spectrum. It is usually denoted by Δ λ {\displaystyle \Delta \lambda } , and is closely related to the resolving power of the spectrograph, defined as R = λ Δ λ , {\displaystyle R={\frac {\lambda…
