THE combination of flash photolysis with absorption spectroscopy has produced a powerful method of investigating transient chemical species and energy-transfer phenomena 1,2. In practice ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

The loss of hydrogen ions by tubular excretion would require the absorption of base from the ... this hypothesis these workers administered sulfanilamide, a specific inhibitor of carbonic ...

and hexane found in the "Atlas of Near Infrared Spectra." 5 Of the four distinct hydrocarbon absorption bands, two bands, 1,180 nm and 1,380 nm, are narrow and sharply defined, though fairly weak ...
