Shock‐driven intramolecular electron redistribution (IER) of cyclotrimethylene trinitramine (RDX) is proposed, which will be helpful for understanding the initiation and safety mechanisms of RDX materials under shock compressions. Laser‐driven shock wave was performed to generate a dynamic pressure, and time‐resolved Raman spectroscopy was used to probe the shock wave response of RDX. First‐principle calculations were utilized to identify Raman modes and determine a pressure‐dependent electron density distribution in RDX molecules. Raman peaks of RDX have blue shifts under shock loadings, which are caused by IER. According to calculations, it can be confirmed that electrons transfer from C–H and N–O bonds to N–N bonds under shock loadings in IER. We suggest that shock‐driven IER will make some chemical bonds be broken more easily under shock conditions.
