A conformer is a clear acrylic shell fitted after an enucleation of the eye [1] if the final artificial eye is not available at the time of surgery, to hold the shape of the eye socket and allow the eyelids to blink over the shell without rubbing the suture line. The conformer shell holds the shape ready for the artificial eye, and is worn for ...
The left hand side is the proportion of conformer i in an equilibrating mixture of M conformers in thermodynamic equilibrium. On the right side, E k (k = 1, 2, ..., M) is the energy of conformer k, R is the molar ideal gas constant (approximately equal to 8.314 J/(mol·K) or 1.987 cal/(mol·K)), and T is the absolute temperature. The ...
An important factor in the antiperiplanar conformer is the interaction between molecular orbitals. Anti-periplanar geometry will put a bonding orbital and an anti-bonding orbital approximately parallel to each other, or syn-periplanar.
The gauche effect is very sensitive to solvent effects, due to the large difference in polarity between the two conformers.For example, 2,3-dinitro-2,3-dimethylbutane, which in the solid state exists only in the gauche conformation, prefers the gauche conformer in benzene solution by a ratio of 79:21, but in carbon tetrachloride, it prefers the anti conformer by a ratio of 58:42.

The molecular motions involved in a chair flip are detailed in the figure on the right: The half-chair conformation (D, 10.8 kcal/mol, C 2 symmetry) is the energy maximum when proceeding from the chair conformer (A, 0 kcal/mol reference, D 3d symmetry) to the higher energy twist-boat conformer (B, 5.5 kcal/mol, D 2 symmetry).
An IBM circuit board from a NASA Space Shuttle computer with a conformal coating applied. Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards (PCBs).
Equine conformation evaluates the degree of correctness of a horse's bone structure, musculature, and body proportions; Conformation (dog) evaluates a dog according to physical standards for its breed
Conformity or conformism is the act of matching attitudes, beliefs, and behaviors to group norms, politics or being like-minded. [1] Norms are implicit, specific rules, guidance shared by a group of individuals, that guide their interactions with others.
