This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Krishnan Raghavachari rather than just read about it. In short: Krishnan Raghavachari (born 3 April 1953, in Chennai, India) is a Professor of Chemistry at Indiana University Bloomington. Raghavachari began his education in his native India, completing his undergraduate degree in 1973 at Madras University and his masters from the Indian Institute of Technology in 1975.

Key takeaways

Krishnan Raghavachari belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Krishnan Raghavachari to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Krishnan Raghavachari from memory before moving on to harder problems.

Reference excerpt

Krishnan Raghavachari (born 3 April 1953, in Chennai, India) is a Professor of Chemistry at Indiana University Bloomington. Raghavachari began his education in his native India, completing his undergraduate degree in 1973 at Madras University and his masters from the Indian Institute of Technology in 1975. Following this, he moved to the United States to attend Carnegie-Mellon University for his doctorate under the tutelage of John Pople, completing it in 1981. Upon completing his degree, Raghavachari entered the private sector as a research scientist at Bell Labs. He served as a member of the technical staff until 1987 when he was named a distinguished member. In 2002, he joined the faculty at Indiana University. Raghavachari has been credited as one of the top quantum chemists in the United States and responsible for developing methods allowing for widespread use of computational chemistry. Among the methods he has developed over his career are CCSD(T), used to evaluate bond energies and the properties of molecules and the Gaussian-2, 3, and 4 methods. Over the course of his career, Raghavachari has given over 150 invited lectures, published over 320 scientific papers, and has been cited over 50,000 times by others in the field. He has also served as chair of the Theoretical Chemistry Subdivision of the American Chemical Society, on the editorial boards of the Journal of Physical Chemistry, Journal of Computational Chemistry, Theoretical Chemistry Accounts, and Journal of Materials Research.

Honours and awards 2009 Davisson-Germer Prize in Surface Physics, American Physical Society 2008 Fellow of the Royal Society of Chemistry 2001 Fellow of the American Physical Society

Worked examples

Example 1 — a first encounter with Krishnan Raghavachari

Start with the simplest possible case. Write down what Krishnan Raghavachari claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Krishnan Raghavachari before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Krishnan Raghavachari ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Krishnan Raghavachari

In research: Krishnan Raghavachari appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Krishnan Raghavachari in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Krishnan Raghavachari is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 21st-century American chemists, 21st-century Indian chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Krishnan Raghavachari outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
