Identifying a Hidden Conglomerate Chiral Pool in the CSD [PDF]
Jacs Au, 2022 Conglomerate crystallization is the spontaneous generation of individually enantioenriched crystals from a nonenantioenriched material. This behavior is responsible for spontaneous resolution and the discovery of molecular chirality by Pasteur.

GRX: a program to search the CSD for functional group exchanges
Journal of Applied Crystallography, 2005In order to establish the effect of exchanging one functional group by another on the crystal structure, one would like to be able to search the Cambridge Structural Database for all pairs of crystal structures where this substitution has been made. A program calledGRX(group exchange) was written for that purpose.

Engineering Solutions for the Next Millennium. 1999 IEEE Canadian Conference on Electrical and Computer Engineering (Cat. No.99TH8411), 2003
This paper is concerned with the development of a technique for the optimization of digital filters over the canonical signed-digit (CSD) coefficient space. Although based on an existing local search algorithm, the proposed optimization technique does not make any recourse to the concept of an optimal scale factor.

Halogen Bond Involving Hypervalent Halogen: CSD Search and Theoretical Study
The Journal of Physical Chemistry A, 2011The Cambridge Structure Database search shows that there are over seventy crystal structures containing halogen bonds in which hypervalent halogens, not monovalent halogens as usual, behave as acceptors of electron density. The nature of the halogen bond involving hypervalent halogen has been investigated by using several theoretical methods with ...

Similarity searching in chemical databases depends crucially upon the chosen molecular attribute sets. The current 2-D implementation in the Cambridge Structural Database System uses substructural bit screens as attributes. These contain chemical information at a restricted connectivity level around each atom or bond; the only larger pattern units ...
