In the simplest experiment the total emission is monitored as a function of excitation frequency, giving an excitation spectrum.

Some static properties of the plasma (similar to the Debye screening length) constrain the excitation spectrum.

The emission spectrum is usually sharper than the excitation spectrum, and it is of a longer wavelength and correspondingly lower energy.

Nearly all mutations of this residue consolidate the excitation spectra to a single peak at either 395 nm or 480 nm.

The excitation spectrum generally is identical to the absorption spectrum as the fluorescence intensity is proportional to the absorption.

The excitation spectra used are broad-band and can be evaluated most effectively using vibration-fatigue methods.

The proper selection of filters requires familiarity with the emission spectrum and the excitation spectrum.

The primary filter is selected to transmit only the wavelengths from the emission spectrum and excitation spectrum that overlap.

Two different kinds of spectra exist, disperse spectra and excitation spectra.

The main suggestion was that quasi-particle excitation spectra might provide distinctive signatures and good criteria for the appropriate choice of the relevant model.
