What is the Sensitivity of my Balance?

Spectral bands are the combination of many different spectral lines resulting from vibrational, rotational and electronic transitions. Unresolved band spectra may appears as a spectral continuum.

Molecular emission is the mechanism behind the sulfur lamp and the deuterium arc lamp.
