What is nmrshiftdb2?

nmrshiftdb2 is a NMR database (web database) for organic structures and their nuclear magnetic resonance (nmr) spectra. It allows for spectrum prediction (¹³C, ¹H and other nuclei) as well as for searching spectra, structures and other properties. The nmrshiftdb2 software is open source, the data is published under an open content license. The core of nmrshitdb2 are fully assigned spectra with raw data and peak lists (we have pure peak lists as well). Those datasets are peer reviewed by a board of reviewers. The project is supported by a scientific advisory board. nmrshiftdb2 is part of the ) are provided. nmrshiftdb2 will work without any special plugins, but at numerous places you can switch to a Java-based version. This gives additional comfort with entering and viewing data, but a prerequisite for your browser is then that the Java VM (virtual machine) must be installed and JavaScript activated. A major problem in the development of Web-based applications is the wide range of ever-changing capabilities and incompatibilities of the popular browsers in use. In the following we offer some comments and tips concerning browser choice, based on current experience, and we welcome your comments.

• Firefox

  Firefox is the recommended browser, which we have extensively tested. We recommend the latest release. Firefox 16 has been tested on Windows and Linux. When you want to use the Java Version of nmrshiftdb2 you should download and install the latest version of the Java 2 VM from the Sun Website.

• Internet Explorer

  IE 8 has been tested and no problems were found. The Sun Java VM should be installed when you want to use the Java version of nmrshiftdb2; when necessary, IE should prompt for this the first time you visit the nmrshiftdb2 site and carry out an automatic installation.

• Opera

  With Opera 7.x (we tested 7.11 build 406) and Java VM all functionalities of nmrshiftdb2 are available. Some versions of Opera 6.x had problems with JavaScript, so the functions Submit, Search and Predict with Java Version do not operate correctly. Please upgrade to Opera 7.

• Konqueror/Safari

  Konqueror =>3.1 and Safari >= 1.2 should work. Older versions do not operate correctly for the functions Submit, Search and Predict with the Java version, due to flaws in Konqueror's JavaScript implementation.

• Macintosh

  On MacOS 10.1 or higher Safari 1.2, Netscape 7.02 and Opera 7.50 (beta) are reported to work with Java VM 1.4.2. On Classic OS, iCab 2.9.7 should work. With other browsers on Macintosh (OS 9 as well as OS X) the so-called "Live-Connect" feature is not available. This means that Submit, Search, Predict do not operate correctly with the Java Version.
