  SETTING UP YOUR EXPERIMENT
 

Enter your sample identification.

It is very important to keep track of your samples, particularly if you have access to a multi-user instrument. Instructions that are only relevant to users of the system at Rider University are shown in red.

Assuming that your first (or only) sample is in NMR CASE slot #1, click on the traffic light icon next to Row #1. A single click highlights the entire row in light blue; a double click creates a new row in preparation for sample information entry. Move your mouse over the screen below to see the new row appear (click here for a larger version of these screens).

     
  If you do not have the NMR CASE, load your sample in the normal way.
   

Select a directory under the Disk column (click for larger screen). If u/class is available, use this directory. Data stored here will be available to NMR-CTP participants over the Internet.
     
Select a location from the available "Name" list. Note that this is simply the subdirectory under which data will be saved; it is not the spectrum title or sample name. Normally, you will store your data under the day's date (larger screen here)
  Set the Experiment Number (Exp No). Note that this will automatically increment if you run more than one sample. Normally, you will start at 1.
   
Select the deuterated solvent used to prepare your sample. Be certain to choose the correct solvent; chemical-shift errors will result from an incorrect selection. Click on the arrow to the right of the solvent box, and scroll down to the appropriate choice. Roll your mouse over the screen below to see this procedure (click here for larger versions)
     
       
Click on the arrow to the right of the Experiment box, and you will see a list of experiments and outputs you may request (click here to see a larger version of the screen below). In all cases, NMR-CTP participants students will see, at least, a series of 1H experiments. Decide whether you want peak picking (pp) and/or integration (int), or simply a plot of the spectrum.
       
     
  There are many parameters that had to be taken into account when these experiments were set up, such as the nuclide to be observed, the chemical-shift range covered, and the conditions that determine whether the spectrum will be quantitative. Normally, you will not need to be concerned about these details, but you can learn more about the process of designing up an NMR experiment by clicking on the button at right.
 
Click on the dialog box button, as shown below (click to view larger screen), to change any experimental parameters you have control over. NMR-CTP participants will, in general, only be able to alter NS, the number of scans. This value should be changed only if it is known that the default value will not yield a sufficiently high signal-to-noise ratio (S/N).
Click on the pad-and-pencil icon. Enter the title (not the file name) for your sample; this will be printed at the top of your spectrum. If you have the option, also specify your name, course, and section.
       
   

Do you want to run more than one experiment on this sample, or do you have more samples to submit? If so, click the button at right to learn how to add samples to the queue.
