Methine methylene methyl
Webhydroxyl proton moves to low frequency, towards the resonance signal of the methyl protons. Unpaired electrons. Shift reagents The interaction between electron and nuclear spin manifests itself as the hyperfine splitting of the signal in ESR experiments. In NMR experiments this interaction leads to a shift of the signal to higher or lower Webmethyl groups (12 protons singlets) at δ H 1.08-1.79 ppm, three methylene groups signals between δ H 2.26–2.56 and the proton doublet broad of olefinic proton at 6.12 (d, J=14.0 Hz). Moreover, the 13C NMR spectrum exhibited 4 quarternary car - bons, 3 methylen groups and 8 methin and methyl groups. At the δ C 120-200 ppm of the spectrum,
