摘要：

The dynamic response of a thin film of the insensitive high explosive 5-nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (NTO) to ultrafast shock compression has been investigated by picosecond coherent anti-Stokes Raman spectroscopy (CARS). Vibrational spectra were obtained in the 1200 cm(-1) to 1450 cm(-1) region with a time resolution on the order of 100 ps. The frequency shifts and widths of the two vibrational transitions in this region show an entirely different behavior when subjected to a shock load of about 5 GPa. An additional weak band at 1293 cm(-1) appears temporarily while the shock front is within the NTO layer.
