| Research Abstract |
Two dimensional correlation spectroscopy have been developed in terahertz frequency region. Terahertz pulse train was generated and two dimensional correlation spectra of gas and solid samples were observed. However, correlation spectroscopy was not successful because power of the produced terahertz pulse was not enough and origin of the vibrational peaks was not clear. We explored materials suitable for the two dimensional spectroscopy and found out that poly-hydroxybutylate shows clear vibrational peaks originated in its higher order conformation, which may show clear correlation in two dimensional spectrum.
