Kevin K. Lehmann

Kevin K. Lehmann is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kevin K. Lehmann rather than just read about it. In short: Kevin K. Lehmann (born September 7, 1955, in Newark, New Jersey) is an American chemist and spectroscopist at the University of Virginia, best known for his work in the area of intramolecular and collisional dynamics, and for his advances in the method of cavity ring down spectroscopy (CRDS).

Key takeaways

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

Reference excerpt

Kevin K. Lehmann (born September 7, 1955, in Newark, New Jersey) is an American chemist and spectroscopist at the University of Virginia, best known for his work in the area of intramolecular and collisional dynamics, and for his advances in the method of cavity ring down spectroscopy (CRDS). Raised in Irvington, New Jersey, a suburb of Newark, Lehmann studied chemical physics and mathematics at Rutgers University's Cook College, graduating with highest honors in 1977. His undergraduate research included work in reaction dynamics with John Krenos and John Tully of Bell Laboratories, photoelectron spectroscopy with Joseph Berkowitz of Argonne National Laboratory, and raman and resonate multiphoton ionization (REMPI) spectroscopies under Professor Lionel Goodman. Lehmann went on to receive his doctorate in chemical physics from Harvard University in 1983, and was elected to the Harvard Society of Fellows, where he was a junior fellow until 1986. Under the direction of William Klemperer, Lehmann's graduate work involved studies of highly excited vibrational states using photoacoustic spectroscopy. During his time as a fellow, he served as a visiting scientist at Massachusetts Institute of Technology's George Harrison Spectroscopy Laboratory. There he developed with Stephen Coy the technique of microwave-detected, microwave-optical double resonance, which permits the automatic assignment of complex spectra. Appointed to the chemistry faculty of Princeton University in 1985, Lehmann received both the Henry and Camille Dreyfus Award for new faculty and the Presidential Young Investigator Award from the National Science Foundation in his first year with the university. In 1987, the university acknowledged him with the Camille and Henry Dreyfus Teacher-Scholar Award. He was promoted to associate professor in 1991, and to full professor in 1995, the same year he was named a fellow of the American Physical Society. He received the Thomas A. Edison Patent Award in 2002 for his work in CRDS, and in 2003, was granted the Earle K. Plyler Prize in Molecular Spectroscopy. Lehmann left Princeton in 2005 to join the faculty of the University of Virginia, where he has continued his work in development of ultrasensitive spectroscopic methods with applications in trace gas detection, as well as studies of molecular dynamics in the gas phase and superfluid helium.

Worked examples

Example 1 — a first encounter with Kevin K. Lehmann

Start with the simplest possible case. Write down what Kevin K. Lehmann claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Kevin K. Lehmann 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 Kevin K. Lehmann 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 Kevin K. Lehmann

In research
Kevin K. Lehmann appears in astronomy 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 Kevin K. Lehmann 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
Kevin K. Lehmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 21st-century American chemists, American chemist stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Kevin K. Lehmann 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.
