Quantum chemical calculations of the equilibrium geometry, harmonic vibrational frequencies, infrared intensities and Raman scattering activities of 2,4,6-trinitrophenol (TNP, C 6 H 3 N 3 O 7 ) in the ground state were carried out by using ab initio HF and density functional theory (DFT/B3LYP) methods with 6-311++G** basis set. The research shows that the presence of...
