The paper explains the relationship between the energy of hydrogen bonds and the distance between associated carboxyl groups of malonic acid (MA) molecules by means of infrared spectroscopic studies of crystals of its four isotopic varieties [CH2(COOH)2, h4-MA; CH2(COOD)2, d2c-MA; CD2(COOH)2, d2m-MA; CD2(COOD)2, d4-MA]. The effects associated with impact on the isotopic dilution and changes in the temperature of spectrum registration on the fine structures of the νO-H and νO-D bands were analyzed. MA molecular crystals are characteri
