Introduction In Part I of this post I briefly described some of the properties of the iodine molecule. The position of iodine in the Periodic
Introduction Iodine. Atomic number 53. Chemical symbol I. Iodine is the rarest of the stable halogens, if we ignore the radioactive elements Astatine (At) and
Measuring the fluorescence from highlighter pens is always an interesting educational experiment to try and is very popular in schools and colleges to demonstrate the basic principles of fluorescence and spectra. Usually, green, blue or violet laser pointers are used to excite the sample.
Absorbance In very general terms, Absorption Spectroscopy is the spectroscopic technique that considers what happens when electromagnetic radiation of any wavelength passes through a
