Abstract:
DESCRIPTION (provided by applicant): We propose to extend the functionality of
our commercial quantum chemistry program, Q-Chem, to effectively treat
molecules containing transition metals. This enhanced capability will provide
Q-Chem's end-users with the ability to accurately model complex molecules such
as proteins, enzymes, and catalysts of industrial importance. While remarkable
progress has been made over the last several years in the accurate modeling of
systems containing transition metals, current numerical methods for achieving
SCF convergence in these systems are problematic at best, resulting in long
execution times or, in some cases, complete failure to find a solution.
However, a novel computational technique developed at Q-Chem has been shown to
dramatically improve convergence for organic molecules with known SCF
convergence problems. We propose to adapt this method for use with transition
metals. Our goal is to achieve the same robust SCF convergence that is realized
for most organic molecules, thereby greatly increasing productivity and
extending the capability of scientists to study molecules such as enzymes and
industrial catalysts. During Phase (I, our efforts will be to further extend
Q-Chem's capability in the molecular biology arena. This proposal seeks to
improve the quantum chemical treatment of molecular systems containing
transition metals. Transition metal elements are essential to natural
biological processes. The technology developed in this research will enable the
computer modeling of those systems that are difficult to handle with the
current methodologies and therefore increase of the applications of
computational modeling.
PROPOSED COMMERCIAL APPLICATION:
Transition-metal elements play a vital role in biological systems. The success of this project will improve the performance of modeling of transition-metal complexes and making the modelings possible for the systems that current algorithms fail. The resulting work will be made available to researchers in health industry and universities through our commercial software Q-Chem.
