... Acid-base titrations are very useful as they allow an accurate determination of an unknown concentration of an acid or a base. In a similar manner, there are many occasions where you may need to know the concentration of a substance that is capable of undergoing an oxidation or reduction reaction. A ...

In Fig. 2(a-c), electrical contacts and hence pumping in the taper region is neglected. However, if we need to ...

Ultraviolet–visible spectroscopy



Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
