Off-line retrieval and processing of data is a considerable advantage of a computer used separately from the spectrometer. 2D WIN-NMR — BRUKER's PC based display and processing package for 2D NMR data matrices — has been designed to fulfill two particular criteria: a variety of different display options allow an interactive interpretation of the 2D data and the best graphical document can be created at the end of the working session. This is accomplished making extensive use of WINDOWS based data transfer capability. For analyzing data separate from the spectrometer it is also necessary to be able to process 2D NMR datasets. 2D WIN-NMR includes all of the standard processing functions an NMR spectroscopist needs and is an easy-to-handle tool for scientific work.
