The prothrombin time ratio is the ratio of a subject's measured prothrombin time (in seconds) to the normal laboratory reference PT. The PT ratio varies depending on the specific reagents used, and has been replaced by the INR. [3] Elevated INR may be useful as a rapid and inexpensive diagnostic of infection in people with COVID-19. [4]
Platinum(II) sulfide is the inorganic compound with the formula Pt S. It is a green solid, insoluble in all solvents. It is a green solid, insoluble in all solvents. The compound adopts an unusual structure, being composed of square planar Pt and tetrahedral sulfide centers. [ 1 ]
The pentahydrate is stable and is used as the commercial form of PtCl 4. Treatment of PtCl 4 with aqueous base gives the [Pt(OH) 6] 2− ion. With methyl Grignard reagents followed by partial hydrolysis, PtCl 4 converts to the cuboidal cluster [Pt(CH 3) 3 (OH)] 4. [6] Upon heating PtCl 4 evolves chlorine to give PtCl 2: PtCl 4 → PtCl 2 + Cl 2
Psi is an ab initio computational chemistry package originally written by the research group of Henry F. Schaefer, III (University of Georgia).Utilizing Psi, one can perform a calculation on a molecular system with various kinds of methods such as Hartree-Fock, Post-Hartree–Fock electron correlation methods, and density functional theory.
n[Pt(CN) 4] 2− → ([Pt(CN) 4] 1.7−) n. Krogmann's salt is a series of partially oxidized tetracyanoplatinate complexes linked by the platinum-platinum bonds on the top and bottom faces of the planar [Pt(CN) 4] n− anions. This salt forms infinite stacks in the solid state based on the overlap of the d z2 orbitals. [2]
Quantities, Units and Symbols in Physical Chemistry, also known as the Green Book, is a compilation of terms and symbols widely used in the field of physical chemistry. It also includes a table of physical constants , tables listing the properties of elementary particles , chemical elements , and nuclides , and information about conversion ...
The parent PT is an insoluble colored solid with the formula (C 4 H 2 S) n. [notes 1] [2] [3] The rings are linked through the 2- and 5-positions. Poly(alkylthiophene)s have alkyl substituents at the 3- or 4-position(s). They are also colored solids, but tend to be soluble in organic solvents.
The bond valence method or mean method (or bond valence sum) (not to be mistaken for the valence bond theory in quantum chemistry) is a popular method in coordination chemistry to estimate the oxidation states of atoms. It is derived from the bond valence model, which is a simple yet robust model for validating chemical structures with ...
