ZAMORANO, Sergio; CAMUS, Juan  and  PIZARRO, Esteban. Structural analysis NMR 1 D and 2D of the 1 -phenyl - 3 - methyl - 2 - pirazolin - 5 - ona - 4 - etoxicarbonil: Calculation of force constant and the bond length of the pair u-o in the uranyl complex. Rev. Soc. Quím. Perú [online]. 2015, vol.81, n.4, pp.339-349. ISSN 1810-634X.

There has been structural analysis of 1-phenyl-3-methyl-2-pirazolin-5-one-4-etoxicarbonil (PirC₂) by means of two techniques of two-dimensional NMR, the HSQC and HMBC, which helped to elucidate the interaction between the atoms of carbon and hydrogen present in the organic molecule. It was interacted this compound with a salt of uranyl in order to test the possible formation of the respective complex compound. Using the vibrational spectrum was possible to determine the force constant and the bond length of the uranium and oxygen atoms at the UO₂ ²⁺ present in the complex, using the model of Badger modified by Jones.

Keywords : Pirazoline derivatives; 1D and 2D NMR spectroscopy.
