摘要: Abstract The barrier heights to the internal rotation of nitro group in 2-nitroresorcinol, 2-nitrophenol, 4,6-dinitroresorcinol, and nitrobenzene have been determined by application a dynamic model electron diffraction data. With Monte Carlo optimization, results are invariant choice particular initial parameter set. motion 4,6-dinitroresorcinol is hindered higher barriers than nitrobenzene, as consequence intramolecular hydrogen bond formation.
