Guest Lecture on “Ultraviolet Spectroscopy: Concept, Theory and Applications”

Mar 28, 2018

Dr Ramesh Kumar, Department of Chemistry, Kurukshetra University, Kurukshetra and having Post Doctoral Research Experience from Taiwan delivered an invited Guest Lecture to Science Students on the topic entitled “Ultraviolet Spectroscopy: Concept, Theory and Applications” in which he discussed 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. He further explained various concepts like determination of structure of an organic compound. He said that in the past, such techniques were laboriously time consuming and sometimes unreliable too. Modern technology has sorted out this difficulty with the advent of spectroscopic methods for determination of structure.

During the lecture Dr. Kumar introduced the electromagnetic spectrum and the origin of transitions giving rise to ultraviolet and visible (UV/Vis) spectra. He further said 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 were also described and the colour origin of certain compounds were major point of discussion.

Such an interactive session for Final Year Students really helps the candidates to groom in professional life along with practical knowledge from the academic and industry expert.
