Absorptions

Absorptions were up 88% in the West region and 87% in the East region year-over-year, with significant increases across all states led by California’s 137% increase.

Europa Infrared spectra taken by NASA 's Galileo spacecraft show distinct absorptions on Jupiter 's moon Europa that have been attributed to one or more sulfuric acid hydrates.

It is possible in some media to use multiple photon absorptions between multiple lower-energy transitions to reach the pump level; such lasers are called up-conversion lasers.

Knowledge of the symmetry properties of the ground and excited states allows one to predict the numbers and intensities of absorptions in vibrational and electronic spectra.

Only the absorption of more than one neutron, a statistically rare occurrence, can activate a hydrogen atom, while oxygen requires two additional absorptions.

Such colors are orders of magnitude more intense than ordinary absorptions seen in dyes and the like that involve individual electrons and their energy states.

These absorptions and emissions, often referred to as atomic spectral lines, are due to electronic transitions of outer shell electrons as they rise and fall from one electron orbit to another.

With this sequence of emissions and absorptions, it takes a long time for radiation to reach the Sun's surface.
