How Q-Chem Got Started

Q-Chem software is distributed by Q-Chem, Inc., a software company based in Pittsburgh, Pennsylvania, USA. It was founded in 1993 as a result of disagreements within the Gaussian company that led to the departure (and subsequent “banning”) of John Pople and a number of his students and postdocs (see Gaussian License Controversy.)

The first lines of the Q-Chem code were written by Peter Gill, at that time a postdoc of John Pople, during a winter vacation (December 1992) in Australia. Peter Gill was soon joined by Benny Johnson (a Pople graduate student) and Carlos Gonzalez (another Pople postdoc), but the latter left the company shortly thereafter. In mid-1993, Martin Head-Gordon, formerly a Pople student, but at that time on the Berkeley tenure track, joined the growing team of academic developers.

Today Q-Chem has grown to involve more than 100 developers in 9 countries around the world. You can read more detail about Q-Chem's history here.

In conjunction with the WATOC 2017 in Munich, Germany (27 Aug. - 1 Sept 2017), we would like to announce a Q-Chem Developers’ Meeting/Workshop to take place on Saturday afternoon, Aug. 26 (exact time and location TBA). The meeting will be free of charge, with food and refreshments provided (but lodging arrangements on you own). The Developer's workshop will be following by the Michael Wormit Award reception and dinner.

In order to get a head count for catering purposes, please send a message to office@q-chem.com if you expect to attend and/or send students and postdocs.

It is our aim to hold a Developers’ Meeting approximately annually. We hope that you can attend this one, and provide you input as to the future of the code!

  • Announcing IQmol!
    Q-Chem is proud to recommend IQmol as its preferred molecular editor and visualization package. IQmol is a free open-source program which offers a range of features that include a molecular editor, surface generation (orbitals and densities) and animations (vibrational modes and reaction pathways).

    IQmol has been integrated with Q-Chem and features an intuitive environment to set up, run and analyze Q-Chem calculations. For more information about IQmol as well as downloading information visit www.iqmol.org.


  • Harvard Clean Energy Project - Powered by Q-Chem
    Q-Chem was recently informed by Harvard that their Clean Energy Project was largely the result of "nearly 40 million DFT calculations with Q-Chem."

    The Harvard Clean Energy Project, motivated by the ever-growing energy crisis, mounts an extensive search for promising photovoltaic organic material which might result in a cheaper and more efficient source of harvesting solar power.  Candidates for photovoltaic applications are screened through molecular calculations performed on more than a million computers, to first eliminate unfit material and provide for structural tends among promising candidates, as well as to examine and provide a more detailed characterization of promising molecules.
