Abstract:
The accurate equilibrium molecular structure of a canonical tautomer of 5-fluorouracil was determined by electron diffraction taking into account anharmonic vibrational corrections calculated with ab initio force field. This structure was applied to benchmark the results of CCSD(T) computations used for the analysis of substitution effects in uracil derivatives.
Keywords:
