Role of O–H⋯O/S conventional hydrogen bonds in considerable C(sp(2))–H blue-shift in the binary systems of acetaldehyde and thioacetaldehyde with substituted carboxylic and thiocarboxylic acids

Stable binary complexes of RCZOH⋯CH(3)CHZ (R = CH(3), H, F; Z = O, S) are due to contributions from the O–H⋯O/S and C(sp(2))–H⋯O/S hydrogen bonds. The strength of C(sp(2))/O–H⋯O is 1.5 to 2 times greater than that of the C(sp(2))/O–H⋯S bond. The substitution of H(C(sp(2))) of HCZOH by CH(3) causes a...
