PROBLEM TO BE SOLVED: To make it possible to easily sense impulsive sensitivity of a detonator comprising a nitramine compound by determining the total of differences between length of N-NO2 bonding in an isolated molecule (in vacuum) and length of N-NO2 bonding in a crystal of a nitramine compound. SOLUTION: An observed length D2 of an N-NO2 bonding in a crystal of a nitramine compound is shorter than a calculated value D1 by a molecular orbital method to an isolated molecule (in vacuum) because of shortening of the N-NO2 bonding in the crystal caused by other molecules existing in the surround. That is, the N-NO2 bonding in the nitramine compound stores energies becoming a trigger of explosion in an initial stage of the explosion. The length D2 of the N-NO2 bonding of a molecule in a crystal of the nitramine compound is different with crystal systems and an impulsive sensitivity of the detonator can be sensed by calculating a length difference of the N-NO2 bonding:δD by using the data in a crystal and in a vacuum.
