【Abstract】 Investigation on vibrational excitation and relaxation process will provide important information 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 v_s（NO₂） and its relaxation process of ground state HNS（2,2’,4,4’,6,6’-hexanitrostillbenein） in solution.The results show that v_s（NO₂） at1385 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.更多还原
