A variety of NMR processing software exist for processing FID files for 1D or 2D NMRs including H-1, C-13, P-31 and other NMR experiments. A few common processing software are listed below.
MestReNova Mestrelabs developed MestreNova which is one of the easiest and commonly used NMR processing software. A free trial of the software is available before purchase.
TopSpin This is a software available from Bruker to process NMRs. This software can also be used to operate Bruker NMRs.
Delta This software was developed by Jeol and can process FID files as well as operate Jeol NMRs.
ACD/Labs This is another commonly used processing software for NMRS
NUTS This software was developed by Acorn and used to process NMRs
ChemDraw and ChemOffice are useful programs for drawing organic molecules and contains features like predict H-1 and C-13 NMR to assist with structural assignments of your molecules
