【名称】nmrdb.org (NMR谱图数据库及NMR谱图预测)
【资源简介】
This is a web-based approach implementing a new java applet that enables to assign a chemical structure to the corresponding NMR spectrum by simply drawing lines between atoms and automatically characterized signals.
This NMR predictor allows to predict the spectrum from the chemical structure based on Spinus (Structure-based Predictions In NUclear magnetic resonance Spectroscopy), which is an on-going project for the development of structure-based tools for fast prediction of NMR spectra developed by Gasteiger (http://www2.chemie.uni-erlangen.de/services/spinus/index.html). SPINUS - WEB currently accepts molecular structures via a Java molecular editor, and estimates 1H NMR chemical shifts.

【名称】BioMagResBank (BMRB): 多肽、蛋白质、核酸等的核磁共振数据存储库
【资源简介】
BioMagResBank (BMRB) is the publicly-accessible depository for NMR results from peptides, proteins, and nucleic acids recognized by the International Society of Magnetic Resonance and by the IUPAC-IUBMB-IUPAB Inter-Union Task Group on the Standardization of Data Bases of Protein and Nucleic Acid Structures Determined by NMR Spectroscopy. In addition, BMRB provides reference information and maintains a collection of NMR pulse sequences and computer software for biomolecular NMR. Access to data in BMRB is free directly from its web site (URL http://www.bmrb.wisc.edu) and ftp site (ftp.bmrb.wisc.edu) and will remain so as public funding permits. The concept of a biomolecular NMR data bank developed under a five-year research grant awarded to the University of Wisconsin-Madison from the National Library of Medicine, National Institutes of Health. This grant was phased out after that period, and a Request for Applications was issued by the NIH for future support of this activity. BMRB at t he University of Wisconsin-Madison won this competition, has been supported since 1 September 1996 by the National Library of Medicine, NIH under grant 1 P41 LM05799. The current award for five years expires on 31 August 2004.
Aims
In collaboration with the Protein Data Bank (PDB, Brookhaven National Laboratories) and Nucleic Acid Data Bank (NDB, Rutgers University), BMRB aims to develop into the collection site for structural NMR data in proteins and nucleic acids. Steps are being taken at BMRB to achieve this capability, which will include transmission of all relevant data to the PDB and NDB collections. In addition, BMRB has the goal of archiving NMR-specific data including assigned chemical shifts, J-couplings, relaxation rates, and chemical information derived from NMR investigations (for example, hydrogen exchange rates and pKa values). In developing these collections BMRB intends to be responsive to the needs and priorities of the scientific community. The operating policy at BMRB is monitored and shaped by its Advisory Board which meets once each year to review progress and set priorities. The Advisory Board is composed of representatives from laboratories that originate and/or use data within the BMRB p urview.

【名称】EPA spectral database
【资源简介】
EPA Reference Absorbance Spectra
The Clean Air Act Amendments (CAAA) was published in November 1990. Title III of the Clean Air Act includes a list of 189 hazardous air pollutants (HAPS) for which test methods must be established. An extractive stack sampling method, using FTIR, has been developed for measuring HAPS. As one of the initial tasks in the project development, reference spectra were developed for as many of the HAPS as possible. Attached is a table which contains the quantitative reference spectral library as of June 1993. The table includes several columns of information for each file. The pathlength is the pathlength of the sample cell used to record that particular spectrum. The TEMP column is the temperature at which the compound was measured. Spectra were recorded for each compound at for at lease two different concentrations when possible. Duplicate spectra were recorded for every concentration for quality assurance purposes. The ASC column is the accepted standard concentration which was assigned b y the chemical standard. The ASC values should be used for data analysis. Duplicate samples were obtained for each concentration. These spectra were developed following the Protocol for Extrative FTIR for Analysis of Gas Emissions . Refer to the FTIR TECHNOLOGY DEVELOPMENT Report for additional information regarding the these spectra.
EPA Reference Spectra Interferograms
Listed are the interferograms from which the EPA Reference Absorbance Spectra were created. Single beam spectra can be created from these interferograms by using the FTPROC program avalible on this site. The Background Interferograms are those interferograms recorded while the absorption cell was evacuated. The Data Interferograms are those interferograms recorded with the analyte present in the absorption cell. The CTS Interferograms are those associated with the recording of the absorption of the Calibration Transfer Standard gas. For more information on the recording of the interferograms please see the report FTIR TECHNOLOGY DEVELOPMENT. The file naming convention used on the interferograms is the same used on the EPA Refernce Absorbance Spectra

【名称】ECDYBASE (The Ecdysone Handbook)
【资源简介】
The " Ecdysone Handbook " was originally created by René Lafont and Ian D. Wilson and published in 1992 by the Chromatographic Society (Nottingham, U.K.). Its aim was to provide general data on all natural ecdysteroids described so far. Each data sheet contained (whenever available) spectroscopic (UV, IR, MS and NMR) and chromatographic data together with a few selected general references. As the ecdysteroid family continued to increase, a second enlarged edition was published in 1996, but the number of compounds is still growing (more than 300 compounds were described at the onset of year 2000).
Owing to the limited number of people interested by such a Handbook, a printed version is no longer justified, and moreover the problem of updating content was a major one. This led to the idea of developing a new concept, making a proper use of modern communication tools. A decision was taken to transform the Handbook in a database made freely available on the web to anyone interested in ecdysteroids.

【资源简介】
This library is a "subset" of one that has been compiled over a period of many years by Dr. Graham Jones and colleagues in Edmonton, Alberta, Canada. Pure drug spectra, plus a few breakdown products and pure metabolite standards have been edited into a single library. The first version of this library contained about 1500 entries. A separate library of metabolites, endogenous compounds and artifacts is under construction, but may be 1-2 years from completion of the first draft (it's an incredibly time consuming process!!).
【检索途径】
The current library is aafsdrug.zip. Click on the file name to download. This file consists of the component files of this library, compressed with the utility pkzip, into a single "zip" file. This saves space and allows a shorter, easier download than if the individual uncompressed files were available. A list of entries can be downloaded separately as an MS Excel v. 4 spreadsheet file that can be viewed with most spreadsheet and many database programs.
Software Compatibility
Libraries made available by the committee primarily designed to be compatible with HP 5970/71/72/73 series instruments that have PC-based DOS/Windows ChemStation operating systems. See the Software Compatibility page for a fuller discussion and the availability of libraries translated for other mass spectrometers.
