| Abstract: | The low frequency vibrational spectrum of crystalline adipic acid has been investigated in the range 20–450 cm−1 at room and low temperatures. The experimental results are compared to ab initio results on a model asymmetric unit. It is shown that the doublet and quartet structures observed for several bands are due to Davydov splitting and Fermi resonance effects. |
