The spectra are "hot-linked" to the molecular graphic display
such that selecting a peak in the IR spectrum will cause a
vibrational mode animation to be loaded, or selecting a peak in
the NMR spectra will cause the appropriate H or C atoms to be
Thanks to Dr Robert Badger for the 400 MHz H NMR spectra and 100
MHz 13C NMR.
The OH proton may exchange with the solvent and this can shift
its position considerably, or even hide it by broadening out the
signal so it is not noticeable at all.
The first spectrum (DMSO) shows a well resolved peak around 13 ppm while
the second (CDCl3/MeOD) shows a well resolved peak at 11.5 ppm. The third
spectrum (Acetone-D6) shows a very broad signal at about 10.5 ppm.
