The Term Intermediate

Many authors may object to our usage of the word intermediate for the spectroscopic excited state at the original geometry, such as trans-stilbene triplet, and there may even be some opposition to the usage of this term for the non-spectroscopic excited state, such as twisted stilbene triplet, and a tendency to reserve the term intermediate only for those species which have a minimum in the So hypersurface. [Pg.23]

The terms intermediate or transitional pores, which have been used in the past, are not recommended. [Pg.367]

The term intermediates refers to tfiose compounds which are prepared from the original coal tar constituents by various chemical procedures and which, in turn, can be converted into commercial dyes by relatively simple further transformations. A typical example is aniline, which is prepared from benzene in various ways, and which can be converted into numerous dyes. [Pg.269]

The canaliculi continue into an ampulla-like extension known as Hering s canal (E. Hering, 1866). This area can be regarded equally as the end point of the canaliculi and the beginning of the ductules, hence the term intermediate ductule is used (M. Clara, 1930). From here the bile ducts have their own wall of cuboidal epithelial cells. They are 7-20 pm in diameter. Their designation as preductules has been generally adopted. (57) Because of their extreme proneness to damage, the preductules are described as the Achilles heel of the liver (L. Aschoff, 1932). [Pg.19]

It is important to recognize the specific meaning of the term intermediate in this context. The use of the term will not relate to the concept of surface complex, or activated complex for, in this case, at least in heterogeneous catalysis, the catalyst, or a part of it, is structurally combined or, by specific force-fields, is interacting with a reaction-participating molecule. In contrast to this meaning, the term intermediate here will refer to a chemical species that is produced by the catalyst as a desorbed, normal chemical species, i.e., one that has its own name, structure, and thermodynamic properties normally associated with indei>endent chemical compounds. [Pg.139]

The term intermediate product means products during the process of production, in which must undergo further necessary manufacturing processes in order to obtain finished products. [Pg.479]

The Administrator does not agree that the term intermediate should be restricted to chemical substances that are totally consumed in chemical reaction processes. A chemical substance may be an intermediate and also appear later as a byproduct or as an impurity. In such circumstances, the substance should be reported for the inventory. [Pg.16]

Phases with noncubic structures were first identified by X-ray scattering from aqueous soap mixtures [68, 69] and anhydrous soap melts in a series of papers by Luzzati and Skoulios [69-73]. In the first of these papers [68] the term intermediate was applied to a rectangular structure found in aqueous mixtures of potassium and sodium oleates and potassium laurate and pal-mitate. The structures found in the anhydrous soaps were reinterpreted as intermediate, tetragonal, rhombohedral, and ribbon structures in the paper by Luzzati and coworkers [74] in 1968. It was not until the early eighties that interest in these unusual phase structures was rekindled. [Pg.356]

Define the term intermediate in the context of reaction mechanisms. [Pg.472]

The quantitative analysis includes three recycling processes a process imder development at the Beijing Institute of Technology (BIT) [16] and intermediate and direct physical processes. We use the term intermediate to indicate that cathodic active material can be obtained from upgrading of process outputs with simple chemical processes, and direct to indicate that process outputs can be reincorporated into batteries with litde or no additional processing. The materials recovered from these processes could be incorporated into the broader economy (open-loop) or reused in Li-ion batteries (closed-loop). Currently, we consider the latter. [Pg.496]

DO-178B always allowed for the possibility of multiple levels of software requirements. For example, DO-178B section 5 refers to one or more successive, lower levels of requirements . An early draft of DO-178B referred to high-level requirements, intermediate-level requirements and low-level requirements. The term, intermediate-level requirements, was felt to be eonftising, so the published text of DO-178B names only two levels of software requirements high-level requirements and low-level requirements. [Pg.298]

The term intermediate syndrome refers to a delayed onset of muscle weakness that occurs shortly after recovery from severe acute effects of OP exposure and... [Pg.746]

Important structures typically include stable intermediates and transition states. In this paper, I will use the term intermediate to refer to any structure between reactants and products and reserve the term stable intermediate for the longer lived species that chemists usually refer to as intermediates. [Pg.310]
