An atom with a steric number of four can have from zero to three lone electron pairs within an sp3 hybridized orbital. Methane, which has no lone pairs, forms a tetrahedron with 109.5-degree bond angles. Ammonia has one lone pair, creating bond angles of 107.5 degrees and a trigonal pyrami...
However, we are not aware of any research work done to evaluate how accurately we can model protein structures with dihedral angles and ideal bond lengths and angles. In this paper, we first introduce the protein structure idealization problem. Then, we develop a fast $O(nm / 系)$ dynamic...
In our previous studies, a rule was formulated referring to how the internuclear distances and the bond angles in a second conformer differ from those in the most stable one. A test of this rule on 36 molecules (existing as two conformer mixtures) showed that it works well for the inter...
Rita is an unappreciated lawyer stuck in a dead-end job, Jessi wants to move on from her presumed-to-be dead husband, and Epifanía intends to move on from her abusive husband. Audiard makes it clear that the women cannot escape the drug cartel world even though they’d like to. Emilia...
Aside from a lower interest rate, you may also have to purchase the new bonds at a higher price. This means you will pay more for a low-yielding bond. Because of this, callable bonds are not ideal for investors who are looking for stable and predictable returns. ...
