  2. 2,6-Dichlorophenol - Wikipedia

    en.wikipedia.org/wiki/2,6-Dichlorophenol

    2,6-Dichlorophenol is a compound with formula C 6 H 3 Cl 2 OH. It is one of the six isomers of dichlorophenol. It is a colorless solid. Its pK a is 6.78, which is about 100x more acidic than 2-chlorophenol (8.52) and 1000x more acidic than phenol itself (9.95). [3]

  3. Dichlorophenolindophenol - Wikipedia

    en.wikipedia.org/wiki/Dichlorophenolindophenol

    2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the ...

    The variables S i 2, η i, α i, β i and γ i are used to denote these 5 parameters for atom i. S i 2 is the magnitude of atom i's motion; η i is a measure of the anisotropy of atom i's motion; α i and β i are related to the polar

  6. Two-dimensional nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Two-dimensional_nuclear...

    In 2D NMR, signals are distributed across two frequency axes, providing improved resolution and separation of overlapping peaks, particularly beneficial for studying complex molecules. This technique identifies correlations between different nuclei within a molecule, facilitating the determination of connectivity, spatial proximity, and dynamic ...

  7. Hyperpolarization (physics) - Wikipedia

    en.wikipedia.org/wiki/Hyperpolarization_(physics)

    Spin exchange optical pumping (SEOP) [3] is one of several hyperpolarization techniques discussed on this page. This technique specializes in creating hyperpolarized (HP) noble gases, such as 3 He, 129 Xe, and quadrupolar 131 Xe, 83 Kr, and 21 Ne. [4] Noble gases are required because SEOP is performed in the gas phase, they are chemically inert, non-reactive, chemically stable with respect to ...

  8. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Angular: Angular molecules (also called bent or V-shaped) have a non-linear shape. For example, water (H 2 O), which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs. Tetrahedral: Tetra-signifies four, and -hedral relates to a face of a solid, so "tetrahedral" literally means "having ...
