Spectroscopy & Spectral Analysis: Advanced Connections

Spectroscopy separates light by wavelength so that continuum shape and spectral lines can be measured quantitatively. Spectroscopy is fundamental to stellar classification, redshift, chemical abundance, exoplanet atmospheres, radial velocity, plasma diagnostics, and galaxy evolution.

Atoms and molecules absorb or emit at quantized energies; motion Doppler-shifts lines; collisions and pressure broaden them; magnetic fields can split or polarize transitions.
