Abstract
Terahertz (THz) absorption spectra of the three isomeric structures of dicyanobenzene obtained from chloroform solutions and the solid phase at 298 K are reported. These spectra exhibit enhanced absorption cross-sections over those measured for most organic systems and are compared to isolated molecule vibrational spectral calculations using Density Functional Theory. Strong experiment and calculation agreement suggest that all internal vibrational modes are readily assigned and comparison to liquid-phase spectra identifies solid-state phonon modes in these weakly associated systems.Citation
