摘　　要：Investigation on vibrational excitation and relaxation process will provide important in- formation for a better understanding of ultrafast dynamic response of energetic materials. Using sub-ps time-resolved coherent anti-Stokes Raman scattering （CARS） experiments, we directly observe excitation of vibrational mode vs（NO2） and its relaxation process of ground state HNS （2,2＇,4,4＇,6,6＇-hexanitrostillbenein） in solution. The results show that vs（NO2） at 1385 cm-1 has been excited and relaxation time of 0.38 and 8.5 ps is obtained. The possible quantum beat frequencies are also discussed via fs-CARS experiments. The original results provide an insight into ultrafast process of energetic materials.
