Looking for raw interferogram data / raw FID data from FT-IR / FT-NIR / FT-NMR
In The Journal of Chemical Education, published by the American Chemical Society, a rather recent article presented a related project, hosted by the University of Minnesota.  Intentionally it is about raw FIDs-as-obtained, out of the NMR spectrometer, aiming to teach correct data processing (including spectra with two orthogonal frequency scales). The article is sponsored by the authors (i.e. freely accessible), the database requires an e-mail to register.  Reference: J. Chem. Educ., 2013, 90 (7), pp 941–943; DOI: 10.1021/ed300787v
