We report the time and frequency-resolved coherent anti-Stokes Raman spectroscopy (CARS) data of nitro-substituted tetrazole-N-(hetero)aryl derivatives with ~ 50 fs pulses. CARS experiments were performed to comprehend the intramolecular vibrational redistribution (IVR) dynamics through vibrational couplings in Amino (6) and Nitro (8) substituted tetrazoles. The present study elevates the applications of tetrazoles derivatives since their energetic properties are comparable with the secondary explosives RDX/TNT. The Fourier transforms of the CARS transients revealed the possible IVR mechanisms in tetrazole-N-(hetero)aryl derivatives. Further, the average coherent vibrational decay time (T₂) were estimated to be in the range of ~120–200 fs from the CARS transients.

我们报告了约50 fs脉冲的硝基取代的四唑-N-（杂）芳基衍生物的时间和频率分辨相干反斯托克斯拉曼光谱（CARS）数据。进行了CARS实验，以通过氨基（6）和硝基（8）取代的四唑中的振动偶合了解分子内振动重新分布（IVR）动力学。本研究提高了四唑衍生物的应用，因为它们的高能特性可与二次炸药RDX / TNT相媲美。CARS瞬态的傅立叶变换揭示了四唑-N-（杂）芳基衍生物中可能的IVR机制。此外，从CARS瞬变估计，平均相干振动衰减时间（T ₂）在〜120–200 fs的范围内。
