Fourier-transform-Raman and infrared spectrum of 4-azatricyclo [5.2.2.0(2,6)] undecane-3,5,8-trione were recorded and analyzed. The vibrational wavenumbers were examined theoretically using the Gaussian03 set of quantum chemistry codes, and the normal modes were assigned by potential energy distribution (PED) calculations.
