They’re not poker-related, but the ICM algorithm models these things as iteratively constructed trees. The internal coordinates of these systems can be represented as Z-matrices. These systems are encoded via ASCII (“ASS-kee”) strings in SMILES notation. Three lines meet at a point in front of a circle in a representation of these things called the Newman projection. A field of “mechanics” named for these systems calculates interactions between them via the Lennard-Jones potential. A line-angle formula represents the “skeleton” of these things, which are commonly represented using ball-and-stick models in classroom demonstrations. For 10 points, materials and computational sciences often study the modeling of what systems composed of atoms? ■END■
ANSWER: molecules [or chemical compounds; accept proteins; accept molecular modeling or molecular mechanics; prompt on atoms or bonds by asking “what larger things are those found within?”; prompt on conformations by asking “of what things?”] (ICM stands for Internal Coordinate Mechanics.)
