The Mole vs. the GUACAMole!

What is a GUACAmole? A guacamole is one single molecule [that is, 1/(Avocado's Number) of moles]. Read the basics of single-molecule spectroscopy in the Research Section for details. Here are few citations noting our definition of "guacamole":

  1. W. E. Moerner, “Optical Spectroscopy of Individual Molecules Trapped in Solids,” AIP Conf. Proc. Vol. 323, AIP, New York, 1995, p. 467.

  2. W. E. Moerner, "High-Resolution Optical Spectroscopy of Single Molecules in Solids," Accounts of Chemical Research, 1996, 29, 563.

  3. K. M. Reese, "Plus ca change, plus c'cest la meme guacamole," Chemical and Engineering News, March 10, 1997, Volume 75, Number 10, p. 200, DOI:10.1021/cen-v075n010.p200

UPDATE 22 May 2019: The 2019 redefinition of the SI base units has redefined the mole by fixing Avogadro's number as a specific integer: NA = 6.02214076 × 1023 mol−1 - that's a lot of zeros after the last six, it seems!

AND THIS IS GREAT, since the definition of the guacamole as one single molecule still stands: a guacamole is (1 / NA) mol !!
