Concentration dependences of the density of aqueous solutions of bisadducts of light fullerene С 60 and essential amino acids are studied by pycnometry. Concentration dependences of the average molar volumes and partial volumes of components (Н 2 О and corresponding bisadducts) are calculated for С 60 (C 6 H 13 N 2 O 2 ) 2 –Н 2 О, С 60 (C 4 H 8 NO 3 ) 2 –Н 2 О, and С 60 (C 5 H 9 NO 2 ) 2 –Н 2 О binary systems at 25°C. Concentration dependences of the indices of refraction of С 60 (C 6 H 13 N 2 O 2 ) 2 –Н 2 О, С 60 (C 4 H 8 NO 3 ) 2 –Н 2 О, and С 60 (C 5 H 9 NO 2 ) 2 –Н 2 О binary systems are determined at 25°C. The concentration dependences of specific refraction and molar refraction of bisadducts and aqueous solutions of them are calculated.
