  "term": "Spectral radiant energy density",
  "field": "Chemistry",
  "definition": "The radiant energy per unit volume per unit interval of wavelength or frequency, describing the concentration of radiant energy within a specific spectral range. It quantifies how much energy is present at each particular wavelength or frequency in a given space. This quantity is typically expressed in units of joules per cubic meter per nanometer (J m⁻³ nm⁻¹) or per hertz (J m⁻³ Hz⁻¹).",
