|Horizontal and vertical zooming is performed by activating the relevant buttons and use the mouse (computer) or zoom and pinch gestures (mobile device). You may always return to the full spectrum view by invoking the full button.|
You have the possibility to make simple postprocessing like phasing the spectrum. |
On a computer, use the left mouse button and drag up or down to phase the spectrum with a zero-order phase shift. If first-order phase shift is required, the position where you did the zero-order phase shift is stored as the pivot point. Then move the cursor to another peak, press the Alt-key and move the mouse up or down to invoke a first-order phase shift.
On a portable device, you use one finger to do a zero-order phase shift, then use two fingers to do a first-order phase shift. The position of your first finger press is the pivot point.
|Peak picking is done by selecting the peak-picking button and use the mouse to select a peak. Click with the mouse over the peak you want to measure. If you are slightly off, it doesn't matter. jsNMR will select the most nearby peak for you.|
|Integration of peaks is done using the mouse. Press the mouse on one side of the peak and drag the mouse to the other side. The selected region will be integrated, and the result will be displayed (in arbitrary units with the weakest peak integrated to 1).|
|Obtain information on the spectral parameters for a given spectrum. This includes the spectral width (sw), reference point (ref, middle of the spectrum), number of points (np), and title.|
Data stored in a jsNMR file is a self-transforming dataset, where you may use the save button to export the data into e.g. comma-separated values (CSV), a new jsNMR file, or into the raw data of the original spectrum. The latter option lets you work with the raw data in other processing software programs.|
Peak lists may be exported to CSV files.
|Delete the current spectrum by pressing this button. The current spectrum is highlighted by an asterisk (*) in front of its title. To select another spectrum as the current, simply click its title.|
|Print the current spectrum. Please be patient, it may take a while.|
