ACD/SpecViewer 4.0 Freeware
http://www.acdlabs.com/download/specview.html
A new program  for viewing and representing processed spectra of different types (NMR, MS, UV, visible, IR, NIR and Raman spectra) through one interface. Requires Chem Sketch.
Also available: commercial software that can simulate NMR spectra of molecules that you draw. One program for ¹H and another for ¹³C. Currently windows version only. Free viewer available. Can download demos and viewer over the internet.
