Next, we will look at ultraviolet-visible (UV-vis) spectroscopy, in which light of a shorter wavelength is employed to provide information about organic molecules containing conjugated p-bonding systems. Mass spectrometery make use of high accelerated electrons instead of EMR, and convert the sample i to small fragments. High-scattering samples can be measured with the smallest of the available interchangeable slits for highest resolution; weak Raman can be measured with a larger slit to allow for increased light throughput. Flame and Plasma Emission Spectroscopy are based upon those particles that are electronically excited in the medium. An interesting, and somewhat related discussion is whether or not a UV/Vis, is a spectrphotometer, or a spectrometer? Third, we have a means of presenting our sample to the spectrometer. The result is usually a calculated measurement of the elements within the metal.
