The 10-micrometre spectral peak of water vapor was absent.
The spectral peaks can be identified by applying the laws of conservation of energy and momentum.
Unlike fluorescence or emission spectra that have characteristic spectral peaks, Cherenkov radiation is continuous.
However, some researchers interpret climate records of the last million years as showing only a single spectral peak at 100 ka periodicity.

Cherenkov radiation does not have characteristic spectral peaks, as typical for fluorescence or emission spectra.
Characteristic spectral peaks are claimed to define one berry's geographic origin from another.
The emitted noise generally appears at sharp spectral peaks (usually at the operating frequency of the device, and a few harmonics).
Heating collapses the blue spectral peak, causing the violet luminescence to shift towards red.
When it acts as a high-pass filter on the white noise with a spectral peak at .
