FT-IR and FT-Raman spectra of acetaldehyde semicarbazone were recorded and analyzed. The vibrational waves were calculated theoretically using Gaussian03 set of quantum chemistry codes. The first hyperpolarizability, infrared intensities and Raman activities are also reported. The calculated first hyperpolarizability is comparable with the reported values of similar derivatives and is an attractive object for future applications in non-linear optics. The geometrical parameters are in agreement with that of reported similar structures.
