What is it about?
This study explores the structure and vibrations of crystalline 4-(dimethylamino) benzaldehyde (4DMAB) using a combination of inelastic neutron scattering (INS) spectroscopy and advanced computational methods. The close match between experimental data and simulations allows for accurate identification of various vibrational modes, including the complex motions of the methyl groups within the crystal. The research provides detailed insights into how these groups move and how their environment affects their behavior, offering a deeper understanding of the material's molecular dynamics. This work contributes to the broader field of molecular crystals by showcasing the effectiveness of combining experimental and theoretical approaches.

Why is it important?
The successful integration of INS spectroscopy and DFT calculations in this study sets a strong example for future research in molecular crystals. By accurately identifying vibrational modes and methyl group motions using a combination of experimental and computational techniques, this research provides valuable insights into the structural behavior of 4DMAB. These findings can inform the design and optimization of materials with similar molecular structures, potentially impacting fields like material science, pharmaceuticals, and chemical engineering.
Perspectives
This work originates from a mission to the TOSCA inelastic neutron scattering spectrometer at ISIS in 2004, which initially aimed to study weak C-H...O hydrogen bonds. Although the original research did not achieve its goal, it led to a new project where periodic DFT calculations were applied to the crystal structure of 4DMAB. This shift in focus allowed us to explore the system through a computational spectroscopy approach, leading to valuable insights into molecular structure and properties.
