Abstract :
In this work, two kinds of phenylthiourea compounds are used as model systems to study the inter-molecular interactions between aromatic rings and the dynamics of the methyl internal rotation which falls into the terahertz region. Experimental and theoretical studies are utilized to identify low-frequency vibrational modes.
