The rotational spectra of four conformers of the acrylic acid—difluoroacetic acid adduct (CH 2 =CHCOOH–CHF 2 COOH, AA‐DFA) are reported and information on their internal dynamics is supplied. This represents an unprecedented result for the conformational analysis, with microwave spectroscopy, of such a heavy molecular adduct.
