CSI

The WLN was applied to indexing the Chemical Structure Index (CSI) at the Institute for Scientific Information (ISI) [13] and the Ituiex Chemicus Registry System (ICRS) as well as the Crossbow System of Imperial Chemical Industries (ICl). With the introduction of connection tables in the Chemical Abstracts Service (CAS) in 1965 and the advent of molecular editors in the 1970s, which directly produced connection tables, the WLN lost its importance. [Pg.25]

Beeause Csy eommutes with the Hamiltonian and Csy ean be written in terms of Lz, Lz must eommute with the Hamiltonian. As a result, the moleeular orbitals (j) of a linear moleeule must be eigenfunetions of the z-eomponent of angular momentum Lz ... [Pg.176]

To determine Cx and Cy, the mixture s absorbance and the absorbances of the standard solutions are measured at several wavelengths. Plotting Am/Asx versus Asy/Asx gives a straight line with a slope of Cy/Csy and ay-intercept of Cx/Csx-... [Pg.402]

Using this data estimate the values for Grand and Csys for the method assuming a = 0.05. ... [Pg.690]

An alternative approach for collaborative testing is to have each analyst perform several replicate determinations on a single, common sample. This approach generates a separate data set for each analyst, requiring a different statistical treatment to arrive at estimates for Grand and Csys-... [Pg.693]

Scintillation detectors are substances which fluoresce when stmck by x-radiation. Scintillation can, therefore, serve to convert x-ray photons into visible or ultraviolet light. Scintillation materials include thaUium-activatedcrystals of sodium iodide, NaI(Tl), potassium iodide, KI(T1), or cesium iodide, CsI(Tl) crystals of stilbene (a, P-diphenylethylene) [588-59-0] and anthracene [120-12-7] bismuth germanium oxide [12233-56-6] ... [Pg.50]

The Af-chlorosulfonyl-4-alkenyl-/3-lactams (119), formed by cycloaddition of CSI with the corresponding dienes, undergo a thermal rearrangement to give the formal [4 + 2]... [Pg.254]

These reactions are reversible by changing the system temperature. ME A also reacts with carbonyl sulfide (COS) and carbon disulfide (CSi) to form heat-stable salts that cannot be regenerated. At temperatures above 245°F a side reaction with CO2 exists that produces oxazolidone-2. a heat-stable salt, and consumes MEA from the process. [Pg.164]

The arylcopper reagents couple with 1-iodoarylacetylenes to give the unsym-metrical diarylacetylenes [25(S] (equation 176) Reaction with tetrabromoethyl- ene gives bis(pentafluorophenyl)acetylene in 66% yield [25S] (equation 177) Pen-tafluorophenyl copper couples with (bromoethynyl)triethylsilane to give C6F5C=CSi(C2H5)3 in 85% yield [259]... [Pg.713]
