[EX Q]: To isolate volatile compounds from nonvolatile impurities, the steam form of this process is used when the compounds decompose at standard temperatures and pressures. Two miscible liquids are heated under a Liebig condenser to increase the concentration of the liquid with the lower boiling point in a common type of this process. FTP, name this separation method by boiling point, whose fractional variety yields cosmetics from petroleum and alcohol from a water mixture.

[EX Q]: One variant of this phenomenon can be used to tune the electronic properties of boron nitride nanotubes from nearly insulating to metallic. Another variant of this phenomenon is induced by interference of standing laser waves to trap atoms of a Bose-Einstein condensate loaded into an optical lattice. Schrdinger's third article from his 1926 series of papers presented his perturbation theory treatment of this effect's modification of the Balmer and Lyman series. Along with van der Waals broadening and resonance broadening, this effect can produce pressure broadening of spectral lines. In addition to the giant version and the AC or Autler-Townes form of this effect, it exhibits variants that are linear and quadratic in the applied field. FTP name this shifting and splitting of spectral lines due to an external electric field, the analogue of the Zeeman effect.
[EX A]: Science

[EX Q]: This poet of the collection Deaths and Entrances wrote that "time held me green and dying / though I sang in my chains like the sea" in "Fern Hill." He depicted the inhabitants of Llareggub in the "play for voices" Under Milk Wood, and eulogized his father in a (*) villanelle which claimed, "Old age should burn and rave at close of day."
