A COMPUTERIZED SPIN TRAPPING DATA BASE

自旋俘获是研究自由电子的一种强大而方便的技术 激进的反应。应用范围广泛，从临床应用 研究高能物理。超过1500篇关于这项技术的参考文献 收录于《化学文摘》。自旋捕获数据库STDBII拥有 已在IBM PC/AT和Mackintosh个人计算机上实现。这个 该程序包运行时不会添加任何“附加组件”。这个程序还很强大 用户友好；命令结构类似于熟悉的1-2-3 灯条菜单；搜索策略采用逐例查询的方法 (QBE)；任何字段的逻辑组合是通过使用AND、OR、 也不是，而且是例外。目前，STDBII(4.5)包含以下文件 5，5-二甲基-L-N-吡咯啉-N-氧化物，α-苯基-N-叔丁基硝酮 2-甲基-2-亚硝基丙烷，α-(4- N-叔丁基硝酮(POBN)、亚硝基(ND)和 3，5-二溴甲基苯磺酸盐(DBNBS)。其他不太受欢迎的数据 陷阱包含在一个包含所有内容的文件中。目前，数据库文件有 2000多个引用，8800多个参数条目。STDBII 文件包含以下信息：1)使用的自旋陷阱；2)自由基陷阱；3) 报告的超细分裂；4)溶剂；5)g值，如果报告的话；6)a 对如何产生和观察自由基的简明描述；7)完整 书目数据。最新版本(STDBII，4.5)也包含动态 关于自旋捕获率的数据以及一个新的参数，NoH值( A(N)/a(H)的比率)，这已被证明对识别 DMPO加合物。STDBII研究人员：1)自旋加合物的鉴定 从有时独特的超精细分裂参数；2)作为关键 将自旋陷阱文献作为纠正已发表错误的工具。 STDBII现在可供NIEHS内外的研究人员使用。这个 软件包包括一本用户手册，其中列出了所有已编译的信息 关于自旋陷阱。目前无法访问IBM/PC的科学家 仍然可以从STDBII中受益，因为所有数据库条目都 印刷在《STDBII用户手册》中。

Spin trapping is a powerful and convenient technique for the study of free radical reactions. The breadth of applications ranges from clinical studies to high-energy physics. Over 1500 references to the technique have accumulated in Chemical Abstracts. STDBII, a spin trapping database, has been implemented on IBM PC/AT and Mackintosh personal computers. The package operates with no "add-ons." The program is powerful yet user-friendly; the command structure is similar to the familiar 1-2-3 light-bar menu; search strategy employs the method of Query-by-Example (QBE); logical combination of any fields is accomplished by using AND, OR, NOR, and EXCEPT. Presently, STDBII (4.5) contains files for 5,5-dimethyl-l-pyrroline-N-oxide (DMPO), alpha-phenyl-N-tert-butyl nitrone (PBN), 2-methyl-2-nitrosopropane (MNP), alpha-(4- pyridyl-1-oxide)-N-tert-butyl nitrone (POBN), nitrosodurene (ND) and 3,5-dibromonitrosobenzene sulfonate (DBNBS). Data for other less popular traps are included in a catch-all file. Presently, the database files have more than 2000 references with over 8800 parameter entries. The STDBII files contain information on: 1) spin trap used; 2) radical trapped; 3) hyperfine splittings reported; 4) solvent; 5) g-value, if reported; 6) a terse description of how the radical was produced and observed; 7) full bibliographic data. The latest version (STDBII, 4.5) also contains kinetic data on spin trapping rates as well as a new parameter, the NoH value (the ratio of a(n)/a(h) ), which has proved useful for the identification of DMPO adducts. STDBII researchers: 1) in identification of spin adducts from the sometimes unique hyperfine splitting parameters; 2) as a key to the spin trapping literature 3) as a vehicle to correct published errors. STDBII is now available to researchers both inside and outside NIEHS. The package includes a user manual that lists all of the compiled information on spin trapping. Scientists who do not presently have access to an IBM/PC can still benefit from STDBII because all of the database entries are printed in the STDBII User Manual.
