網頁입체 효과(立體效果, steric effect)는 분자의 입체구조로 인한 반응성의 변화를 말하며, 이때문에 반응속도가 느려지는 것을 입체 장애(立體障礙, steric hindrance)라고 한다. 같이 보기 … 網頁2014年5月19日 · The steric overlap volume in cubic Angstroms Note: The overlap volume is calculated as a sum of pair-wise steric clashes. This may double count overlaps for very severe steric clashes where there are really three spheres overlapping.
網頁2024年9月16日 · Author summary Template-free protein structure prediction remains an important unsolved problem. We proposed a new pipeline to construct full-length protein structures by coupling multiple-level deep learning potentials with fast gradient-based folding simulations. The large-scale benchmark tests demonstrated significant advantages in … 網頁A textbook case of twisted structure due to hydrogen–hydrogen steric clash, the biphenyl molecule, has been studied in real space from a new perspective. Long-term discrepancies regarding the origin of the steric repulsion are now reconciled under the NCI (Non Covalent Interaction) method, which reflects in
網頁2016年4月23日 · Here is a link to a Wikipedia article on A-Values. Look at the table of A-Values in this article. A methyl group has an A-Value of 1.7 kcal/mol. a phenyl group has an A-value of 3 kcal/mol.

網頁A molecule’s steric hindrance can be used to favor a specific reaction. For example, there are two types of substitution reactions, Sn1 and Sn2. Both of these reactions can be performed with simple molecules; however, Sn1 can occur with bulky molecules, while Sn2 cannot because it is too congested for the mechanism known as a ‘backside attack’.
