It successfully uses a material's band structure to explain many physical properties of solids, such as electrical resistivity and optical absorption.

Apart from optical absorption, boron acceptors have been detected by electron paramagnetic resonance.

Thus the interstitials remain near the original vacancies and form vacancy-interstitials pairs identified through optical absorption.

In contrast, silicon does react with vacancies, creating the described above optical absorption at 738 nm.

It is known that optical absorption is closely associated with physiological properties, such as hemoglobin concentration and oxygen saturation.

This animated image was acquired using near infrared radiation at 800 nm, where optical absorption by blood is higher than surrounding tissues.

The Franz-Keldysh effect is a change in optical absorption by a semiconductor when an electric field is applied.

Experimentally more directly accessible properties of the polaron, such as its mobility and optical absorption, have been investigated subsequently.

Measurement of the temperature, pressure, or density changes that occur due to optical absorption are ultimately the basis for the photothermal spectroscopic measurements.

It turns out that a similarly broad description exists for extraordinary optical absorption as well.
