Apakah Raman Effect itu? Ketemu di Encyclopedia.com: ... the appearance of additional lines in the spectrum of monochromatic light that has been scattered by a transparent material medium. The effect was discovered by C.V. Raman in 1928.
Salam, RM EXCELLING IN SCIENCE PROFESSOR S UMAPATHY Studying chemical structures What does Raman spectroscopy have to do with pharmaceutical industry? Lots, if the person in question is Professor S Umapathy, Department of Inorganic and Physical Chemistry, Indian Institute of Science, Bangalore. SUBBALAKSHMI B M What does Raman spectroscopy have to do with pharmaceutical industry? Lots, if the person in question is Professor S Umapathy, Department of Inorganic and Physical Chemistry, Indian Institute of Science, Bangalore. Winner of the Shanthi Swarup Bhatnagar award for excellence in science and now ready to receive the C V Raman award for research into the contemporary application of Raman Spectroscopy, Professor Umapathy and his team of researchers are working on methods to identify and understand the different crystalline forms of a chemical in drugs. In a conversation with Deccan Herald, the Professor explained his work and what awards mean to him. Here are the excerpts. Give us a brief insight into your work. My area of specialisation is application of Laser techniques to study molecular structures. Specifically we use the principles of Raman effect (RAMAN SPECTROSCOPY) to understand changes in chemical structures as the chemical reaction proceeds. This is very important if we have to understand most of the chemical reactions around us. Understanding such microscopic details of structures would help us in controlling reactions and therefore improve the efficiency by designing new structures with the desired properties. What are you currently working on? We are working on number projects right now. One of them is related to pharmaceutical industry. Here, we are trying to develop Raman spectroscopic methods to identify and understand polymorphism (different crystalline form of a chemical) in drugs. Another project deals with studying a chemical structure while it undergoes chemical reaction at the same speed as it happens. We are also ready to set up a laser centre, to study chemical and physical processes using the ultrafast lasers, in collaboration with Professor Ajay Sood. You have been conferred the Bhatnagar award as well as C V Raman award for excellence in science. For which projects did you get them? These awards are not for a specific project but for the work we have carried out over the last five to ten years in India, which has been recognised both nationally and internationally. Our research contribution is in contemporary application of Raman Spectroscopy (named after Sir C V Raman) to molecular structures. We have set up a state-of-the-art laser laboratory for such a study and carried out number of experiments to gain knowledge into the changes in molecular structures during the course of a chemical reaction. Your comments on receiving the awards. The awards such as these are a recognition of consistent performance at the national and international level. I would say, one works hard and enjoys doing science for its shear fun and creativity and awards are bonuses to encourage people to continue to do well. Do awards and associated recognition help scientists get closer to the public? Do they help better communication? Awards like these, I would like to think, does help communicate with the public more easily. I do believe it is important for scientists to communicate the excitement in science and value of scientific research and advancement. However, awards can only bring scientists get closer to the public if and when media takes interest in these aspects. This way, public learn about developments in science and engineering in our country and perhaps motivate young people to get into the field of research. I always believed that media have considerable responsibility in educating the public; in particular, making the public more knowledgeable. Has the focus of today’s scientists changed to working towards getting an award? I don’t think so, I hope not anyway. I doubt anyone who is a sincere and motivated scientist would work towards an award. It is not realistic to work towards any award in science, even if it is for a Nobel Prize. ------------------------ Yahoo! Groups Sponsor --------------------~--> Make a clean sweep of pop-up ads.
