Ultraviolet-Visible (UV-Vis) Spectroscopy – Fieser-Kuhn Rules to Calculate Wavelength of Maximum Absorption (Lambda-max) of Polyenes (with Sample Problems)
Number of Views : 15Introduction Woodward-Fieser rules work well for conjugated dienes and polyenes with upto 4-double bonds or less. Certain plant pigments such as carotenoids have even more than 4 conjugated double bonds. For conjugated polyenes having more than 4 double bonds, the Fieser-Kuhn rules must be applied in order to obtain the wavelength of maximum absorption. Fieser-Kuhn Rule…

A Primer on Measuring Concentrations – Molarity, Moles and Other Confusing Stuff
Being pharmacy and pharmaceutical science students, we face concentrations all around us in some form or the other. This article is aimed to guide you better on how you can do the calculations and understand what is going on while calculating concentrations. We start off with the definition of Avagadro’s Number, cover gram molecular weight, moles, molarity etc. and will end with real life example problems with solutions which you can use to practice your calculations with.
