Reactivity and Mechanism in Organic Chemistry

為了解決Rearrangement的問題，作者Zipse, Hendrik 這樣論述：

Completely revised and updated, this 2nd Edition of Reactivity and Mechanism in Organic Chemistry is an ideal introduction to the quantitative description of organic reactivity for students in undergraduate and masters chemistry programmes. The book proceeds logically from qualitative molecular o

rbital theory as a tool for the description of bonding phenomena to combining this with thermochemical data to rationalise concepts such as molecular strain and hyperconjugation. Next, transition state theory, for examining organic reactivity phenomena, is introduced and its relation to energy surfa

ces and simple rate equations is discussed. On this basis more specific reactivity concepts commonly used in organic chemistry are explored such as the Bell-Evans-Polanyi principle, Marcus theory, HSAB principle, Hammett correlations, the Mayr-Patz equation, and FMO theory. How these reactivity mode

ls are applied is demonstrated for pericyclic reactions and selected rearrangement reactions involving transient intermediates such as radicals, diradicals, or carbocations, and for reactions involving classical electrophile/nucleophile combinations.

布里斯洛中間體自由基反應機制之理論研究

為了解決Rearrangement的問題，作者謝明修 這樣論述：

含氮雜環卡賓（N-heterocyclic carbene）催化之化學反應中，布里斯洛中間體（Breslow intermediate）扮演重要的催化角色。布里斯洛中間體能以親核基（nucleophile）或自由基（radical）之形式參與反應。本論文探討布里斯洛中間體之自由基特性及形成機制（mechanism），其自由基可從氫自由基轉移或直接氧化形成。安息香縮合反應（benzoin condensation）中，布里斯洛中間體將氫原子轉移至苯甲醛（benzaldehyde）以形成自由基，此自由基可結合形成安息香產物，或排除反應之副產物，使其重新進入催化反應。唯此路徑之反應能障高於傳統非自

由基路徑。此研究亦探討四種布里斯洛中間體之不同電子組態的位能面。其中烯醇鹽（enolate）形式能產生偶極束縛態（dipole-bound state），此為產生自由基之新路徑；拉電子基（electron-withdrawing group）以及立體障礙基（bulky groups）可穩定基態。另外，我們亦研究布里斯洛中間體之碎片化（fragmentation）與重組（rearrangement）。布里斯洛中間體之催化反應可能因其碳氮鍵斷裂而中止，形成碎片。我們證實其反應中可以形成自由基，亦可形成離子。反應趨向之路徑與布里斯洛中間體之羥基的質子化型態有關。碎片化反應亦可視為轉酮醇酶（tran

sketolase）中之噻胺（thiamin）催化反應中之副反應；此研究證實轉酮醇酶透過限制布里斯洛中間體之結構與質子化型態，使其碳氮鍵斷裂需更高之反應能量，進而抑制此副反應。

Lucretius on Disease: The Poetics of Morbidity in >de Rerum Natura

為了解決Rearrangement的問題，作者Kazantzidis, George 這樣論述：

The standard view in scholarship is that disease in Lucretius’ De rerum natura is mainly a problem to be solved and then dispensed with.However, a closer reading suggests that things are more layered and complex than they appear at first sight: just as morbus causes a radical rearrangement of ato

ms in the body and makes the patient engage with alternative and up to that point unknown dimensions of the sensible world, so does disease as a theme generate a multiplicity of meanings in the text. The present book argues for a reconsideration of morbus in De rerum natura along those lines: it inv

ites the reader to revisit the topic of disease and reflect on the various, and often contrasting, discourses that unfold around it. More specifically, it illustrates how, apart from calling for therapy, disease, due to its dominant presence in the narrative, transforms at the same time into a conce

pt that is integral both to the poem’s philosophical agenda but also to its wider aesthetic concerns as a literary product.The book thus sheds new light on De rerum natura’s intense preoccupation with morbus by showing how disease is not exclusively conceived by Lucretius as a blind, obliterating fo

rce but is crucially linked to life and meaning-both inside and outside the text.

同步加速器光源中插件磁鐵的進階特性之研究

為了解決Rearrangement的問題，作者羅皓文 這樣論述：

本論文中研究了在現在與未來升級後的台灣光子源中三個與聚頻磁鐵技術有關的主題，第一是相位可調式聚頻磁鐵(adjustable phase undulator)，有別於傳統聚頻磁鐵藉由調整磁列間隙達到改變共振光子能量的方式，相位可調式聚頻磁鐵則是改變磁列的縱向相對位置調整光子能量，然而此種操作模式在橢圓極化模式中會產生無可避免的磁場橫向梯度場(~100 T/m)，此梯度場不但有機會降低同步輻射光源的品質還有可能改變儲存環中電子團的的工作條件，解析模型被提出以估計橫向梯度場對光源與電子團品質的影響，數值方法用來驗證解析模型對光源品質的估計。第二個主題是在雙極小值垂直貝塔函數(betatron fu

nction)磁格中的串聯式聚頻磁鐵，為了達到更好的聚頻磁鐵輻射與電子團的橫向相空間匹配，三個四極磁鐵被安裝在儲存環的直段中間壓低垂直貝塔函數，然而，將一台聚頻磁鐵分成兩台和插入其中的四極磁鐵都造成聚頻磁鐵輻射中額外的相位延遲與軌跡的改變，導致傳統估計聚頻磁鐵輻射品質的方法不適用於此種特殊光源，基於維格納分布函數(Wigner distribution function)的數值方法被用來計算此種光源的光源亮度，相關的主題如光源的橫向同調性與兩台聚頻磁鐵的校準也一併討論。最後一個主題是1:3利薩如曲線（Lissajous curve）式聚頻磁鐵，在傳統聚頻磁鐵中加入額外的不同週期長度磁列改變電子

軌跡，達到降低近軸區域的輻射功率分布以減輕下游光束線中光學元件的熱附載的效果，初步的概念設計說明這樣的磁場分布與大小以現有的光學元件實際上是可以達到的，推廣版的聚頻磁鐵輻射解析表達式被用來評估聚頻磁鐵輻射的品質與降低熱附載的效果並以聚頻磁鐵輻射數值計算軟體驗證。
