and visible (vis.) light spectroscopy. It is clear that useful chemical information is also found in the near infrared (n.i.r.) and this region is therefore included in the chapter. With the dimensions of the clay particles comparable to the wavelength, it is impossible to distinguish the ...
This book provides a low-level introduction to the fundamentals and practical aspects of ultraviolet/visible spectroscopy, the most commonly used and versatile techniques in analytical chemistry. The second edition includes chapters on the increasingly used new derivative techniques, as well as new exampl...

Ultraviolet and visible spectroscopy deals with the recording of the absorption of radiations in the ultraviolet and visible regions of the electromagnetic spectrum. The ultaviolet region extends from 10 to 400 nm. It is subdivided into the near ultraviolet (quartz) region (200–400 nm) and the...
Ultraviolet/visible (UV/VIS) absorption spectroscopy has been used in the clinical laboratory for many years. The technique has appeal, as it is almost universal in its application. Although much of the routine work is performed using high-throughput dedicated clinical analysis systems, absorption sp...
