abstract = "The signal/noise ratio of a scanning spectrometer in the spectral region where shot noise is not limiting (sub-stantially the λ ≥ 1 μ region of the infrared spectrum) can be expressed as

[Equation 1]

where *SNR*
_{sc}(ν) is the signal/noise ratio as
a function of ν, *f*(ν) is the spectral density function of the spectrum measured at resolution Δν, *a* is the noise equivalent power of the detector, *b* is the relative fluctuation amplitude of fluctuations in the source, sample, or measuring system, *T*
is the total measurement time, and ν_{1}, ν_{2} the scan limits.",
