Abstract :
The vibrational spectra of water clusters in the gas phase are calculated by using Ab initio calculation and molecular dynamics. The result reveals that the non-chiral water molecules have circular dichroism (CD) effect due to the hydrogen bondings between the molecules. Strong absorption and circular dichroism have been observed in THz range.
