First, you will need to create a standard file.  Create an empty file by typing edc.  Then type rpar, which brings up a big window.  Look for the nuclei of interest, eg., P31, Si29, B11, etc., and click on the choice, then click OK.  Then you must type getprosol to complete the standard file setup.

Once you have the standard file, the rest is similar to running a 1H or 13C experiment.  On 400, you will need to run atma.

Some nuclei have several options in the rpar window.  For example, P31CPD is P31 with proton decoupling, while P31 is without the decoupling.  You can run both and compare the spectra and look for the difference.

F19 only works on DPX300 (B622 Conte).  You can only select F19 (not F19CPD) in rpar window.  31P and 13C work on both DPX300 and Avance400 (LGRT room 075).  All other nuclei can only be done on Avance400.
