The activated Spectrum window with the corresponding buttons in the button panel are shown.

This section describes the function of the most important buttons in the button panel (Fig. 4.2). Some of the additional options available within the Display pull-down menu in the main menu bar of 1D WIN-NMR and the function of scroll bars and function keys will be discussed in sections 4.5.2 and 4.5.3 respectively. All affect the display of a spectrum or FID in the ID WIN-NMR [Spectrum] window. The display buttons (Fig. 4.7) are available, whenever the ID WIN-NMR program has been started. 

With ID WIN-NMR the panel title indicates the current operational mode of the button panel, either ID for the spectrum window or Text, Relaxation or Preview for the corresponding windows. The function of the buttons in the panel change to reflect the functionality of the selected mode. 

The next three buttons change the current mode of the mouse pointer, which affects how the pointer behaves in the window which shows the spectrum. The current mouse pointer mode can be changed by clicking with the left mouse button on one of these buttons (which become highlighted). The current mouse pointer mode is also indicated by the shape of the pointer in the spectrum window. 

Button for placing a spectrum cursor on the top of peaks in the spectrum Maximum Cursor mode). Selecting this mode automatically inserts an info line at the top of the spectrum window which lists information about the pointer position, i.e. the x- and y- co-ordinates of the spectrum cursor in Hz/ppm, the number of the associated data point and its intensity. 

The next buttons in the button panel are highlighted when active and are toggles which may be used to alter how data is displayed in the spectrum window ... 

The functions of the additional buttons available with the ID WIN-NMR [Spectrum] window are as follows ... 

When an FID or spectrum is read into the spectrum window, the following short-cut buttons for rapid access to the most frequently applied processing, display, edit and plot tasks are available. For most of these buttons a dedicated dialog box to set up and adjust the corresponding parameters is available by clicking with the right mouse button. 

If an FID is read into the spectrum window, special FID short-cut button.s are available. Their functionality will be discussed in chapter 5. 

Click this button to exit from the current button panel mode, and return to the display ground state of the spectrum window from which another function with its own button panel mode may be chosen. Selecting an entry from the pull-down menu bar in the main menu automatically causes a change in the display ground state of the spectrum window. The Return key on the keyboard has the same function. 

This command performs the same operation as the ALL button in the Spectrum window button panel. It resets the x- and y-axis scales so that the complete speclrum/FID i.s visible. 

Clicking this button opens a new dialog box showing all the various options available for the current display mode of the Spectrum window. The contents of this dialog box depend on which display mode is currently active different content.s are visible for the normal, dual and multiple display modes. Use the Help tool for more detailed information. 

This option lets you define colors for the elements in the Spectrum window. Again the self-explanatory dialog box opened by this option depends on the currently selected display mode (normal, dual, multiple). 

The scroll bars in the Spectrum window let you scroll the spectrum in the x- and y-... 

After defining a plot area by means of the x-Area... and y-Area... buttons, the user can still change the display of the spectrum in the Spectrum window. The Show Area button resets the display in the Spectrum window to the same as in the plot. 

Elements from Spectrum Window to be plotted Printer Setup... 

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 button opens a dialog box in which you may select the font to be used in plotter or preview output for the spectrum window (scale, peak picking, integral). It does not affect the fonts for the parameter and the title window. 

Click the Output Font... button and define the output fonts for and the style according to your preferences. Note that this influcences only the fonts in the Spectrum window (peak picking values, scale (ppm/Hz) values), but not the fonts for the title and parameter windows of the plot layout. The latter fonts may be set with the Preview option (4.7.3). 

Sends the plot as a vector-oriented metafile to the MS-WINDOWS clipboard from where it can be transferred into any other MS-WINDOWS program. The plot area of the output is taken from the currently displayed area in the Spectrum window. Parameter lists and the title cannot be transferred using this method. They can be copied by transferring the output, including the title and lists, first into the Preview window, from where it may be copied to the MS-WINDOWS clipboard using the Copy option in the Edit pull-down menu in the Preview window menu bar. 

Lets you view the history file, which contains all the commands for the current processing session that have changed the data in the Spectrum window. 

Expand Causes a dialog box to appear on screen, which allows you to define the regions in both dimensions of a 2D spectrum, either in ppm or Hz. For quick expansions the mouse may be used within the spectrum window. 

Amplitude of the signal (linearity of the cell, use the oscilloscope and frequency spectrum window)... 

The NDR can be explained by the field effect, which splits the resonance scattering lines because of the frequency shifts at the turning points, and therefore the electron flow only partly contributes to the current. In accordance with the Pauli principle, the Fermi energy spectrum window given by the difference of Fermi functions results in a step-like increase of the current, when being overlapped with the transparency resonance at the bias voltage equals a multiple of the phonon quantum nil, as shown in Fig. 1. Since the transparency doublets are split faster than the Fermi windows are broadened out, after a... 

All the processing steps in this section are intended to enhance the time domain data leading to the suppression of distortions or artefacts and an improvement in the overall spectral quality. The suitability of the methods can be estimated from the appearance of the FID in the main spectrum window of ID WIN-NMR as illustrated in the schematic FID shown in Fig. 3.6. The envelope of the exponentially decaying FID has a dc offset as it is not symmetrical about the zero line whilst the spectrum lineshape may be improved by either zero filling or apodization or possibly both. 

The primary function of the buttons in the top part of the button panel is to change the appearance of the data displayed in the spectrum window irrespective of whether the data is a FID or spectrum. The functionality of these buttons is independent of the current processing command whilst the lower part of this panel may contain addition buttons specific to the current task. The special buttons for allowing the comparison of two or more spectra discussed in section 3.2.3.4 in combination with the output options. 

The upper part of the ID WIN-NMR button panel, in conjunction with the scroll bars along the edge of the window, contains all the functions necessary for expanding and panning through the data displayed in the main spectrum window. This panel also contains the buttons for changing the cursor mode. With the exception of the Zoom button all the buttons are activated by a single click of the left mouse button. 

The command Process I Window Function opens the Specify Window Function dialog box where a window function can be selected and the associated parameters selected. Clicking the Interactive button the parameters may be optimized interactively both the FID and the window function are loaded into the main spectrum window and the parameters adjusted using the slider box in a special button panel. Clicking the Window button using the right mouse button opens the Window Function dialog box where both the function and parameters may be selected.
