Abstract: Density-functional theory calculations at the WB97XD/6-311++G* * level of theory are presented to characterize the hydrogen-bonding interactions between ciproftoxacin and methacrylic acid during the pre-polymerization stage in molecular imprinting. Ciprofloxacin is an antibiotic characterized by multiple selective sites that can interact with an acid monomer. The reactivity was analyzed using natural bond orbital charges. The nucleophilic and electrophilic centers become more negative and more positive, respectively, after complex formation. A combination of geometrical parameters, atomic charges analysis and theoretical IR spectra are used to predict the hydrogen bond strength. The counterpoise method for the mitigation of basis set superposition error was used. By means of these results, it is possible to better understand these H-bonding interactions between the ciprofloxacin molecule, acting as template, and the methacrylic acid
