SSC Description

The plot of the direct SSC reveals that the value of the direct SSC does not depend on the molecular geometry. This fact demonstrates that this is mainly a first-order effect, thus justifying the use of first-order perturbation theory for its description. Moreover, it becomes obvious that the SSC contribution to the ZFS is significant and cannot be neglected in a quantitative description. 

The original objective of the EUROTRAC project LACTOZ was to provide kinetic and mechanistic data to enable a quantitative description of the tropospheric ozone budget in numerical models. Following the review by the EUROTRAC-SSC in 1991 the priorities set for the second phase of LACTOZ were understanding... 

This SAR provides a description of the HCF and its operations, an assessment of the hazards and potential accidents which may occur in the fecility. The potential consequences and likelihood of these accidents are analyzed and described. Using the process and criteria described in DOE-STD-3009-94, safety-related structures, systems and components are identified, and the important safety functions of each SSC are described. Additionally, information which describes the safety management programs at SNL are described in ancillary chapters of the SAR. 

Numerous theoretical studies on both early and late transition metal SSCs have appeared in recent years covering nearly all aspects of the olefin polymerization process (for reviews, see Refs. 282 and 283). The employed methodologies include molecular mechanics (284-291), ah initio electronic structure methods (292-297), density functional studies (298-303), as well as various hybrid techniques (304-308), such as the combination of quantum and molecular mechanics (QM/MM). A detailed description of these studies is outside the scope of this article nevertheless, these theoretical investigations have played a major role in elucidating the elementary steps of olefin complexation, chain propagation, and chain termination as well as the mechanisms of stereocontrol in catalytic olefin polymerization.
