Terahertz spectroscopy of cyanobenzaldehyde isomers

Cyanobenzaldehyde isomers have been investigated using THz spectroscopy demonstrating several distinct resonances from 2 to 21 THz. DFT simulations have been carried out to understand the origin of resonances which show good agreement with experimental results. THz spectroscopy of isomers provides valuable information for designing molecules with customizable THz resonances.
