lineshape

Example:The spectroscopic profile of the helium emission spectrum is well-defined and distinct.

Definition:The characteristic form or appearance of a spectral line as observed in spectroscopic analysis.

Example:The spectral distribution of solar radiation is measured to understand the energy balance of Earth's atmosphere.

Definition:The amount of radiation of a given wavelength emitted or absorbed by a substance, often visualized as a lineshape.

Example:The spectrum of light from a prism is a classic demonstration of the dispersion of white light into its constituent colors.

Definition:A range or series of wavelengths or frequencies of electromagnetic radiation, often represented as a lineshape in spectroscopy.
