Study of hydrogen bond between N-phe-nyl, N'-isopropyl-N- phenylenediamine and N,N'-diphenyl-N- phenylenediamine molecules
Frequencies and low frequency shifts of νNH valence vibrations in IR spectra of N-phenyl, N'-isopropyl-n- phenylenediamine and N,N'-diphenyl-n- phenylenediamine forming hydrogen-bonded complexes in binary melts which manifest synergism in tire rubber have been studied. Experimental results are in agreement with DFT quantum chemical calculations.
