Abstract It was established by IR spectroscopy and quantum-chemical calculations along nonempirical DFT method in B3LYP version with the basis set 6-311 G (d, p) that 2, 2- dibromovinyl trifluoromethyl ketone consisted of a mixture of s-cis planar conformer and s- trans-form deviating from a plane by 13°, whereas the s-cis-form is more energetically stable than the s-trans one (ΔE-5.07 kcal mol-1). Also in 2, 2-dibromovinyl methyl ketone the ...
