Structure unknowns using 1H, 13C, IR, and MS
spectra

In these
problems you are given the molecular formula of the unknown and then at
least
the H NMR spectrum from which you should be able to work out a
structure. As
the molecules get more complicated you are given C NMR data, as well as
IR and
Mass spectra in many cases.

Thanks
to the NMR archive at Pacific Lutheran University for some of the 1H and 13C NMR
data and the NIST Webbook
for some of the IR and Mass spectral data ("IR and Mass Spectra" by
NIST Mass Spec Data Center, S.E. Stein, director, NIST Standard
Reference Database Number 69, Eds. W.G. Mallard and P.J. Linstrom,
