Abstract :
Single frequency coherent terahertz-wave generation method is used to obtain low-frequency spectra of the hydrogen bonding organic small molecules. Transmission spectrum of each sample show several peaks in this region. On the other hand, ab initio frequency calculations are performed for each molecule by CRYSTAL06 package. Both experimental results and theoretical calculations are compared each other.
