免费的谱图数据库.docVIP

免费的谱图数据库20个 ★ ★ ★ ★ ★ 【名称】ChemExper化学品目录CDD (包括MSDS、5000张红外谱图） 【资源简介】 The database contains currently more than 70 000 chemicals, 16000 MSDS, 5000 IR spectra and more than 20 suppliers. It is the only chemical database that lets you SUBMIT your own data! 【检索途径】 You can find a chemical by its molecular formula, IUPAC name, common name, CAS number, catalog number, substructure or physical characteristics 【地址】http://www.chemexper.be/ 【名称】 (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. 【地址】/ 【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】 Introduction 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 ) and ftp site () 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 Na
