UV Spectroscopy uses ultraviolet light to determine the absorbency of a substance. In simple terms, the technique maps the interaction between light and matter and measures. As matter absorbs light it undergoes either excitation or de-excitation, which generates what is known as...

UV-Vis spectrophotometry is a powerful analytical technique used in various scientific fields to measure light absorbance across the electromagnetic spectrum’s ultraviolet (UV) and visible (Vis) ranges. By measuring the intensity of light passing through a sample solution and comparing it to the inte...
Benzene is colorless but its isomer fulvene is yellow. How will you explain it by UV-Visible spectroscopy? If you did not have melting point data, could IR spectroscopy be used to differentiate among the three possible unknown drug components? Explain why or why not?
Optical Spectroscopy Optical spectroscopy (or UV-Vis spectroscopy) is a versatile, non-invasive technique widely used to study a range of different materials. Useful for probing solutions, thin films, or bulk devices, it can help you determine the material properties and molecular structure of you...

UV-VIS spectroscopy in the biomedical arena. At Duke, for example, Wax and colleagues have been developing cellular assays in a lab-on-a-chip format − using UV spectroscopy to analyze functionalized gold nanoparticles, for example. This is “a good way to get biophotonics technologies into ...
How can spectroscopy be used to identify the presence of specific elements in a substance? What are chemical indicators? How are they used in titrations? What are the two most common types of scanning probe microscopes? How was UV-visible spectrophotometer used to relate the abs...
