抄録

We investigated the origin of terahertz (THz) energy decay, upon THz generation by difference frequency generation (DFG), of 1-methyl-4-{2-[4-(dimethylamino)phenyl]ethenyl}pyridinium $ p$-toluenesulfonate (DAST) derivatives by density functional theory (DFT) calculations. The strong energy decays at 8.5 and 7.6 THz were found to originate from the in-plane ring deformation vibration of the anion part of DAST and 1-methyl-4-{2-[4-(dimethylamino)phenyl]ethenyl}pyridinium $ p$-chlorobenzenesulfonate (DASC), respectively.
