Similar to benzene, borazine has 6π electrons, with these being formally contributed by the nitrogen atoms. A calculated π-donation of ~ 0.5 e from the nitrogen atom to the vacant π-orbital of boron is accompanied by a strong polarisation of the σ-skeleton, imparting a negative charge to nitrogen and a positive charge to boron.If the inline PDF is not rendering correctly, you can download the PDF file.for relevant news, product releases and more.degruyter.com uses cookies to store information that enables us to optimize our website and make browsing more comfortable for you.

However, borazines do not show evidence for ring-current effects. Resonance structures of borazine. To determine: The Lewis and resonance structure of the molecule Borazine (B 3 N 3 H 6). The Electronic Structure of Borazine as seen by 10 B, 11 B, and 14 N Nuclear Quadrupole Double Resonance A. Lötz 1 , J. Voitländer 1 and J. 1971, 10, 775.Huober, J.; Pfeffer, M.; Ruoff, A. Chem. The borazine 3 was fully characterised by multinuclear NMR spectroscopy, FTIR and mass spectrometry. 2001, 627, 589.Watson, J. K. G. J. Mol.
Ges. The high-resolution FTIR spectrum of the fundamental ν8 of borazine 10B3 14N3 1H6 was reanalyzed taking into account the α BB resonance with the combination band (ν10 + ν17). Explanation of Solution. A parameter set for the states ν8 = 1 and ν10 = ν17 = 1, respectively, is given, reproducing the observed spectrum at least up to J = 30 with experimental accuracy.
1926, 59, 2215.Niedenzu, K.; Sawodny, W.; Watanabe, H.; Dawson, J. D.; Tutani, T.; Webe, W. Inorg. The nuclear quadrupole double-resonance spectra of the two isotopic forms of borazine, B 3 14 N 3 H 6 and B 3 15 N 3 H 6 , have been obtained at 77 K in the frequency range 50-2000 kHz, and a definite assignment of the 14 N frequencies made. A number of theoretical studies support a substantial extent of aromatic character. A novel Townes-Dailey type of analysis was employed to obtain the electron distribution in borazine.
