  2. Tier list - Wikipedia

    en.wikipedia.org/wiki/Tier_list

    A tier list is a concept originating in video game culture where playable characters or other in-game elements are subjectively ranked by their respective viability as part of a list. Characters listed high on a tier list of a specific game are considered to be powerful characters compared to lower-scoring characters, and are therefore more ...

  3. 2,2'-Dipyridyldisulfide - Wikipedia

    en.wikipedia.org/wiki/2,2'-Dipyridyldisulfide

    2,2′-Dipyridyldisulfide, sometimes known as DPS, is used for preparing thiols [1] [2] and activating carboxylic acid for coupling reactions, as in the following reaction: [3] Uses [ edit ]

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    NMR and FRET methods can be used to determine complementary information including relative distances, [4] [5] [6] dihedral angles, [7] [8] angles, and connectivity. Molecular geometries are best determined at low temperature because at higher temperatures the molecular structure is averaged over more accessible geometries (see next section).

  5. Descriptive geometry - Wikipedia

    en.wikipedia.org/wiki/Descriptive_geometry

    Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions by using a specific set of procedures. The resulting techniques are important for engineering, architecture, design and in art. [1]

    3), carbonate (CO 2− 3), and guanidinium (C(NH 2) + 3). In organic chemistry, planar, three-connected carbon centers that are trigonal planar are often described as having sp 2 hybridization. [2] [3] Nitrogen inversion is the distortion of pyramidal amines through a transition state that is trigonal planar.
