Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

We use a new approach to characterize the absorption characteristics of chromophoric dissolved organic matter (CDOM) in standard solutions and in several tropical lake ecosystems (Lake Victoria, Lake ...

IT is well known that the study of the absorption spectrum of elements provides us with the simplest method of determining the normal states of atoms. In the hands of Wood, Bevan, McLennan, and ...

Trurnit, H. J., and Colmano, G., Biochim. Biophys. Acta, 31, 434 (1959).

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

What is UV-Vis Spectroscopy? UV-Vis spectroscopy, short for ultraviolet-visible spectroscopy, is an analytical technique that measures the absorption or reflectance of light by a sample in the ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting ...
