Abstract
Acetone and cyclohexane make a binary azeotrope with mole ratio 3:1. Some characteristic vibrational modes of acetone and cyclohexane change due to the azeotrope formation. The extend of interaction of these molecules causes significant changes on vibrational modes involved, and 1H NMR signals show some changes on their position. FTIR and 1H NMR spectra of pure substances and corresponding azeotrope were recorded, mutual influences resulting from azeotrope formation have been analyzed, spectral changes have been discussed. The unit-structure of cluster were deduced based on mole ratio, boiling point depression of constituents and comparison between spectra obtained by FTIR and 1H NMR techniques.
