Chromium hexacarbonyl is a symmetric molecule with a strong infrared absorption due to stretching of its six carbon monoxide groups.

Further efficiency and durability has been obtained by introducing disorder to the lattice structure of the surface layer of titanium dioxide nanocrystals, permitting infrared absorption.

The infrared absorptions of the principal natural greenhouse gases are mostly in two ranges.

Special high-Q crystals, for use in highly stable oscillators, are grown at constant slow speed and have constant low infrared absorption along the entire Z axis.

The Raman frequency is 523 cm and another infrared absorption is at 580 cm.

Two approaches have been used to measure the response of polymer systems to infrared absorption.

So water is likely doing most of the infrared absorption.

Eventually, the infrared absorption increases so much that the amount of energy escaping to space no longer depends on the temperature at the surface, and asymptotes to a fixed value.

In this phase it exhibits a dark-red color, very strong infrared absorption, and a magnetic collapse.

Near infrared absorption features indicate the presence of variable amounts of low-iron, low-calcium orthopyroxenes on the surface.
