Single beam spectrum

{
  "id": "MLC-T-CHM-010887",
  "term": "Single beam spectrum",
  "field": "Chemistry",
  "definition": "A measurement of the intensity of radiation transmitted through or reflected from a sample, recorded as a function of wavelength or wavenumber, without reference to a background or blank. This raw spectral data includes contributions from the light source, optical components, and the detector response. It is often ratioed against a background spectrum to obtain a transmittance or absorbance spectrum.",
