Ga⁺ 1次イオンTOF-SIMSにおける有機化合物の開裂推定

—多原子分子における結合解離エネルギーに着目して—

抄録

Fragmentation of some organic compounds is inferred in terms of bond-dissociation energies of the atoms in those compounds. A big role of the dissociation energy for the fragmentation can be recognized, but fragmentation and ionization process are complex compared to the case of fragmentation of inorganic compounds. Besides the dissociation energy, proton transfer, formation of sub-stable ion, recombination of fragment radicals, cyclization etc. should be considered during the Ga⁺ primary ion irradiation.
