However evidence suggests most of the color change occurs rapidly, in the first hundred thousands years, limiting the usefulness of spectral measurement for determining the age of asteroids.

The mass spectral measurements separated into eight groups.

Remote spectral measurements present several challenges compared to laboratory measurements.

In addition, spectral measurements can be used to determine the accuracy of theoretical predictions.

Quantum efficiency is most usefully expressed as a spectral measurement (that is, as a function of photon wavelength or energy).

Since some wavelengths are absorbed more effectively than others, spectral measurements of quantum efficiency can yield valuable information about the quality of the semiconductor bulk and surfaces.

The most accurate determination comes of course from spectral measurements, but there is not always enough time to get qualitative spectra with high signal-to-noise ratio.

Spectral intensity is the corresponding spectral measurement of intensity; in other words, the intensity as a function of wavelength.

Based on the measured temperature of the lava and the spectral measurements, some of the lava may be analogous to terrestrial komatiites.

By comparing spectral measurements of the star's light before and during the planetary transit, for example, they hope to find out what the planet's atmosphere is made of.
