The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
This process is repeated, each time with atoms one bond farther from the stereocenter, until the tie is broken. (19 words)
The energy barrier for the inversion of the stereocenter is relatively low, e.g., ~7 kcal/mol for a trialkylamine. (20 words)
More definitions * A configurational stereoisomer is a stereoisomer of a reference molecule that has the opposite configuration at a stereocenter (e. (21 words)
However, one should note that adding a chemical group to the prochiral center from the re-face will not always lead to an S stereocenter, as the priority of the chemical group has to be taken into account. (38 words)
If the relative priorities of these substituents need to be established, R takes priority over S. When this happens, the descriptor of the stereocenter is a lowercase letter (r or s) instead of the uppercase letter normally used. (38 words)
Cycles To handle a molecule containing one or more cycles, one must first expand it into a tree (called a hierarchical digraph by the authors) by traversing bonds in all possible paths starting at the stereocenter. (36 words)
Example sentences (11)
After the substituents of a stereocenter have been assigned their priorities, the molecule is oriented in space so that the group with the lowest priority is pointed away from the observer.
Assignment of priorities R/S and E/Z descriptors are assigned by using a system for ranking priority of the groups attached to each stereocenter.

The energy barrier for the inversion of the stereocenter is relatively low, e.g., ~7 kcal/mol for a trialkylamine.
The same rules that determine the stereochemistry of a stereocenter (R or S) also apply when assigning the face of a molecular group.
They rank the atoms around a stereocenter in a standard way, allowing the relative position of these atoms in the molecule to be described unambiguously.
This means that configurational isomers can be interconverted only by breaking covalent bonds to the stereocenter, for example, by inverting the configurations of some or all of the stereocenters in a compound.
This process is repeated, each time with atoms one bond farther from the stereocenter, until the tie is broken.
