Rezumat:

NMR spectra of azulen-1-yl diazenes, Schiff bases and corresponding ethenes are discussed in order to find the correlation between the compound structures and the chemical shifts of the protons or carbon-13. Some of the above-cited compounds were protonated and the modification in chemical shifts produced by this process was investigated.
