Try out the effect of the correspondingly available buttons in the button panel: Linear, Log. This data can then be used to extract structural information relating to internuclear distances. As a consequence the signal-to-noise ratio is usually optimized, i. Proton H-C 1 with resonance at 5. Set up a display with projections in both F1 and F2, adjust the relative sizes of the 2D spectrum and the projections and activate the grid to facilitate subsequent spectral analysis. Auto Scale Reset Zoom Mode. The parameters associated with these more specialised ilems have been discussed in the previous sections.

In contrast to the preparation and the detection period which are part of any pulae sequence, the evolution and the mixing period are not necessary i n all types of N M R experiments. It is unlikely that the storage capacity of floppy diskettes will increase substantially in the near future, so with the exception of 1D data sets, using this method for file import cannot be recommended. Hit the Finish button to exit the installation program. Applying your own ideas you should plot the corresponding spectra and try to unravel the unknown structure of this compound. It is the aim of this presentation, to demonstrate the most popular experiments used for measuring various nuclear properties, e.

I am very grateful to Dr H. This Job buttons option is most convenient and an alternative to the Serial Processing option to manually process a few or even series of data files in the same way. Make sure that the Auto Arrange to Paper option is set. This cosmetic operation should be used in situations where either you do not want to symmetrize a spectrum because of the possible loss of information or 5. Use the Change One button to adjust the value of the lowest positive level. Click on the Separate button to initialize the multiple display which consists of 7 equal windows each containing a single spectrum with its own x-axis. Use the mouse to select a suitable expansion.

The Linewidth option in the Analysis pull-down menu allows you t o nieiisiii. For the determination of exchange and relaxation rates the method of saturation transfer was applied. Pulse Diagram 'H-Decoupler channel P1 D1 I 'H-Observe channel Fig. Click on the Symj button to symmetrize the spectrum. This will open a corresponding dialog box for selecting one of the computation methods, for defining the region to be cleaned and for executing the computation.

The Page Layout dialog box appears, click on the Print button to produce a plot. Print Items that are currently active in the Spectrum window can be selected for the hardcopy or Preview output by checking the respective filters in the Display Options group. This converted data will be processed in chapter 5. At the same time corresponding local mode buttons appear in the button panel Fig. Allows you to set the screen colors contour levels, background.

Decrease the contour level values for the negative diagonal peaks by at least a factor of 10. Save the peak picking regions in the corresponding region file. It may be that the memory size of your output device is not large enough with respect to the required printing, that the option for a full page plot is disabled or that a configuration parameter for the output device has not been set correctly. Fourier transformation and phasing the spectrum, are discussed. If the number of dummy scans in a 2D experiments is set too low, data acquisition may be started before a steady-state e. Load the saved integral regions again Load Int.

Acetoxytropyliumbromide 9 is formed from tropone and acetylbromide. An info text appears on the inlet and the new Reset Levels button is displayed. Use the Copy all function in the Output pull-down menu to copy this layout into the clipboard. Note that for heteronuclear 2D spectra, especially weak samples, the signal-to-noise ratio is the crucial factor. ~ The integration buttons panel has several functions: Slider Var.

Initiate the plot with the Print. The main steps for transforming raw I D and 2D data into the corresponding spectra are shown in Figs. Second, the processing and display is done on good data sets. Para button and allows the selection of the acquisition parameters to be included in the plot. Simple graphics elements such as lines or rectangles may be created and added and different types of fonts for text and lists are available.
