Abstract :
We have investigated molecular aggregates of dimethylsulfoxide (DMSO) in cyclohexane to study the weak hydrogen bond between S=O and H-C using terahertz time-domain spectroscopy and FT-IR absorption spectroscopy. It is suggested that formation of different types of DMSO aggregates are observed in mid-IR and THz absorption.
