1000 characters  Quantum chemistry has become an invaluable complement to experimental observations.  High accuracy quantum chemical  modelsfor properties  have effectively achieved _predictive power_ power_, helping understand chemical phenomena  with fundamental essential  physical insights insight.  _Chirality_ is the unique property   \emph{Chirality} is the unique property possessed by molecules with a  three-dimensional ``handedness'' so that their mirror images cannot be  superposed, Fig. \ref{fig:chirality}.  \begin{wrapfigure}{l}{0.4\textwidth}  \vspace{-10pt}  \includegraphics[width=.35\textwidth, center]{Chirality_with_hands}  \vspace{-20pt}  \caption{Chiral molecules exist as \emph{enantiomers}:  mirror images that are not superimposable, like the left  and right hands \cite{chirality}.  }  \label{fig:chirality}  \vspace{-10pt}  \end{wrapfigure}  The project will enable high accuracy calculations of chiroptical properties for large molecular systems.
