The course introduces the three key spectroscopic methods used by chemists and biochemists to analyse the molecular and electronic structure of atoms and molecules. These are UV/Visible , Infra-red (IR) and Nuclear Magnetic Resonance (NMR) spectroscopies. The content is presented using short focussed and interactive screencast presentations accompanied by formative quizzes to probe understanding of the key concepts presented. Numerous exercises are provided to facilitate mastery of each topic. A unique virtual spectroscopic laboratory is made available to enable students to measure and analyse spectra online. Assessment is via summative quizzes completed during the course period.

You will enjoy this course very much even if you haven't studied it in your Grad school. The explanations are very easy to understand. Although it's a short course but it is quite informative.
From the lesson
Ultraviolet and Visible Spectroscopy
In this first week we introduce the electromagnetic spectrum and the origin of transitions giving rise to ultraviolet and visible (UV/Vis) spectra. You will learn that electronic transitions are caused by absorption of radiation in the UV/Vis region of the electromagnetic spectrum. The reason for the wavelength and intensity of bands will be described and the colour origin of certain compounds will be discussed. You will also be shown how UV/Vis spectroscopy is performed and you will be able to run and analyse your own spectra. As the final activity in this module you are given a link to view how to obtain a UV/Visible spectrum in the laboratory. Good luck, try and participate in the discussion forums to enhance your learning and don't forget to complete the end of week laboratory quiz which contributes to your final mark.
