TY - JOUR JF - opsi JO - ICOP & ICPET _ INPC _ ICOFS VL - 24 IS - 0 PY - 2018 Y1 - 2018/3/01 TI - Trinitrotoluene Infrared Absorption Spectrum TT - طیف جذب مادون قرمز تری نیتروتولوئن(TNT) N2 - Trinitrotoluene (TNT) is used as propellant and explosive. Detection of this compound is of great importance from security and environmental pollution stand points. In this research, Infrared (IR) spectrum of TNT is recorded. Next, the structure and vibrational frequencies of normal modes of TNT molecule are computed by electronic – structure calculations. By companies on of the IR peaks of TNT in the computed vibrational frequency, each IR peak is assigned to the corresponding normal mode of vibration. The results of the present work can be applied to the identifications of TNT by lasers working in IR region.
