Strain and nonbonded atoms

The medium-size rings (7 to 12 ring atoms) are relatively free of angle strain and can easily take a variety of spatial arrangements. They are not large enough to avoid all nonbonded interactions between atoms. [Pg.42]

Steric strain differences in the monomer and polymer arising from bond angle deformation, bond stretching, or interactions between nonbonded atoms. [Pg.276]

Steric strain (Section 6.1) Strain caused by repulsion between nonbonded atoms that results in distortion of bond lengths and/or bond angles. [Pg.1277]

In addition to angle strain and torsional trdin. stertr Mrain is yet a third factor that cont ributes to the over l strain energy of cycloalkanes. As in gauche butane (Senonbonded atom in o molecule repel ua other if they approach tcK> closely and attoropt to occupy the same... [Pg.143]

The following conformations, free from angular strain, can be postulated for bicyclo[3.3.1]nonane itself chair-chair, CC (2a), chair-boat, CB (2b) boat-boat, BB (2c). Although conformations 2a-2c are free from angular strain, none is free from strong destabilizing interactions between nonbonded atoms. In order to discuss the experimental and computational data more systematically, it is necessary to consider the factors that stabilize and destabilize conformation 2a-2c. [Pg.173]
