Group Theoretical Vibrational Analysis of 4-Chlorobenzaldehyde

K. S. Satheeshkumar

Abstract: In this paper, vibrational analysis of 4-chlorobenzaldehyde is been carried out using the principles of group theory in chemistry. At first the symmetry elements were analysed and point group was derived to be Cs. Based on the character values and number of unshifted atoms for each symmetry operation, its reducible representation was obtained which later converted into irreducible representations. Using the character table, the IR active and Raman active vibrations were found out. Finally, the IR spectra of 4-chlorobenzaldehyde was also discussed.
