In-situ High Pressure Study of an Elastic Crystal by FTIR Spectroscopy

Abstract

We performed an in-situ high pressure FTIR spectroscopic study on 2,3-dichlorobenzylidine-4-bromoaniline (DBA) crystal at pressures ranging from ambient pressure to 13.8 GPa at room temperature. The variations in the stretching frequency of the aromatic C–H, H–C=N and C–Cl bands on compression showed significant molecular movement in the DBA crystal. Decompression was monitored on the C–H aliphatic and aromatic stretches which clearly show the reversibility of the molecular movements in the crystal lattice.
