标题: Bruker TOPSPIN 2.1 使用方法(文件,原始数据)
摘要: 请问大家,Bruker TOPSPIN 2 1处理核磁图,ABS APK PLOT等命令是怎样的输入顺序啊……
请问大家,Bruker TOPSPIN 2.1处理核磁图,ABS APK PLOT等命令是怎样的输入顺序啊网友回复一般你拿到原始数据了输入efp,abs,apk之后就可以进行处理了~plot不知道是干嘛的~~网友回复原来plot是打印啊~网友回复 引用内容:
一般你拿到原始数据了输入efp,abs,apk之后就可以进行处理了~plot不知道是干嘛的~~ abs,好像不用输也可以,plot是打印的意思网友回复刚下的这个软件,想请问topspin2.1怎么打开数据,我点open没有数据文件显示。网友回复 引用内容:
刚下的这个软件,想请问topspin2.1怎么打开数据,我点open没有数据文件显示。 我现在遇到同样问题,你是怎么解决的啊?谢谢网友回复 引用内容:
我现在遇到同样问题,你是怎么解决的啊?谢谢... 先abs三遍,再apk三遍,处理完了,最后plot输出就可以啦网友回复 引用内容:
先abs三遍,再apk三遍,处理完了,最后plot输出就可以啦... 我现在解决了,谢谢啊网友回复怎么用啊。把拷回来的数据放哪个文件夹?打开发现没有数据。

怎么用啊。把拷回来的数据放哪个文件夹?打开发现没有数据。
:cry: 放在/data//nmr/
:Windows是C:/Bruker/TOPSPIN
Linux是/opt/topspin
中應有data, exp, plot, prog等文件夾
第一個是用戶名稱,基本上可以任意改(需英數),但最好用自己的名稱以方便管理
第二個是樣品名稱,同樣可以任意改(需英數)
第二個後應有代表實驗次數的數字文件夾,每個文件夾代表一個NMR實驗
如你有一個樣品有三個實驗,第一個實驗的數據應放在C:/Bruker/TOPSPIN/data/user001/nmr/sample001/1,第二及三個放在/sample001/2及/sample001/3网友回复 引用内容:
放在/data//nmr/
:Windows是C:/Bruker/TOPSPIN
Linux是/opt/topspin
中應有data, exp, plot, prog等 ... 怎么还是不行显示没有数据,求赐教,

淘豆网网友近日为您收集整理了关于NMR常见溶剂和杂质氢谱和碳谱化学位移的文档,希望对您的工作和学习有所帮助。以下是文档介绍:NMR Chemical Shifts monLaboratory Solvents as Trace ImpuritiesHugo E. Gottlieb,* Vadim Kotlyar, andAbraham Nudelman*Department of Chemistry, Bar-Ilan University,Ramat-Gan 52900, IsraelReceived June 27, 1997In the course of the routine use of NMR as an aid anic chemistry, a day-to-day problem is the identifica-tion of signals deriving mon contaminants(water, solvents, stabilizers, oils) in less-than-analyti-cally-pure samples. This data may be available in theliterature, but the time involved in searching for it maybe considerable. Another issue is the concentrationdependence of chemical shifts (especially 1H); resultsobtained two or three decades ago usually refer to muchmore concentrated samples, and run at lower icfields, than today’s practice.We therefore decided to collect 1H and 13C chemicalshifts of what are, in our experience, the most popular“extra peaks” in a variety monly used NMRsolvents, in the hope that this will be of assistance tothe practicing chemist.Experimental SectionNMR spectra were taken in a Bruker DPX-300 instrument(300.1 and 75.5 MHz for 1H and 13C, respectively). Unlessotherwise indicated, all were run at room temperature (24 ( 1°C). For the experiments in the last section of this paper, probetemperatures were measured with a calibrated Eurotherm 840/Tdigital thermometer, connected to a thermocouple which wasintroduced into an NMR tube filled with mineral oil to ap-proximately the same level as a typical sample. At eachtemperature, the D2O samples were left to equilibrate for at least10 min before the data were collected.In order to avoid having to obtain hundreds of spectra, weprepared seven stock solutions containing approximately equalamounts of several of our entries, chosen in such a way as toprevent intermolecular interactions and possible ambiguities inassignment. Solution 1: acetone, tert-butyl methyl ether, di-methylformamide, ethanol, toluene. Solution 2: benzene, di-methyl sulfoxide, ethyl acetate, methanol. Solution 3: aceticacid, chloroform, diethyl ether, 2-propanol, tetrahydrofuran.Solution 4: acetonitrile, dichloromethane, dioxane, n-hexane,HMPA. Solution 5: 1,2-dichloroethane, ethyl methyl ketone,n-pentane, pyridine. Solution 6: tert-butyl alcohol, BHT, cyclo-hexane, 1,2-dimethoxyethane, nitromethane, silicone grease,triethylamine. Solution 7: diglyme, dimethylacetamide, ethyl-ene glycol, “grease”(engine oil). For D2O. Solution 1: acetone,tert-butyl methyl ether, dimethylformamide, ethanol, 2-propanol.Solution 2: dimethyl sulfoxide, ethyl acetate, ethylene glycol,methanol. Solution 3: acetonitrile, diglyme, dioxane, HMPA,pyridine. Solution 4: 1,2-dimethoxyethane, dimethylacetamide,ethyl methyl ketone, triethylamine. Solution 5: acetic acid, tert-butyl alcohol, diethyl ether, tetrahydrofuran. In D2O andCD3OD nitromethane was run separately, as the protonsexchanged with deuterium in presence of triethylamine.ResultsProton Spectra (Table 1).1播放器加载中,请稍候...
