ABSTRACT

Bond and molecular polarizabilities of uracil and its substituents are determined by molecular vibration and quantum mechanical delta-function potential model. The longitudinal bond polarizability coefficients of C4-C5, C5-CH3 and C5-NO2 bonds confirm that position 5 is partially aromatic while position 4 is aliphatic with reference to the reactivity nature of carbon atoms in uracil. The results are discussed in relation to experimental and theoretical results.
