Photodissociation dynamics of ${\text{CO}}_{\text{2}}^{+}$ vibrationally mediated via its ${\tilde{A}}^{\text{2}}{\mathrm{\Pi }}_{\text{u,1/2}}\left({\upsilon }_1,{\upsilon }_2,0\right)$ and ${\tilde{B}}^{\text{2}}{\mathrm{\Sigma }}_{\text{u}}^{+}\left(0,0,0\right)$ states in the wavelength range of 282–293 nm has been investigated using the time-sliced velocity map imaging technology by probing the $\text{C}{\text{O}}^{\text{+}}$. An initial transition from ${\tilde{X}}^2{\prod }_{g,1/2}\left(0,0,0\right)$ to ${\tilde{A}}^2{\mathrm{\Pi }}_{\text{u,1/2}}{\left(\text{5},\text{2},0\right)}_{\kappa }$ followed by strong vibrational coupling between the ${\tilde{A}}^2{\mathrm{\Pi }}_{\text{u,1/2}}{\left(\text{5},\text{2},0\right)}_{\kappa }$ and ${\tilde{B}}^2{\mathrm{\Sigma }}_{\text{u}}^{\text{+}}\left(0,1,0\right)$ states is suggested to attribute the origin of the five unassigned peaks in the photofragment excitation spectrum. Since the two-photon energy of 8.46–8.80 eV is close to 8.9 eV, the ${\text{CO}}_{\text{2}}^{+}\left({\tilde{C}}^2{\mathrm{\Sigma }}_g^{+}\right)$ state is dissociated by the mechanism of Praet et al.

的光解离动力学 ${\text{一氧化碳}}_{\text{2}}^{+}$ 通过其振动介导 ${\stackrel{〜}{\mathrm{一种}}}^{\text{2}}{\mathrm{\Pi }}_{\text{u，1/2}}\left({\upsilon }_{\mathrm{1个}}，{\upsilon }_2，0\right)$ 和 ${\stackrel{〜}{乙}}^{\text{2}}{\mathrm{\Sigma }}_{\text{ü}}^{+}\left(0，0，0\right)$ 使用时间切片速度图成像技术，通过探测282-293 nm波长范围内的态 $\text{C}{\text{Ø}}^{\text{+}}$。从最初的过渡${\stackrel{〜}{X}}^2{\prod }_{G，\mathrm{1个}/2}\left(0，0，0\right)$ 至 ${\stackrel{〜}{\mathrm{一种}}}^2{\mathrm{\Pi }}_{\text{u，1/2}}{\left(\text{5}，\text{2}，0\right)}_{\kappa }$ 其次是 ${\stackrel{〜}{\mathrm{一种}}}^2{\mathrm{\Pi }}_{\text{u，1/2}}{\left(\text{5}，\text{2}，0\right)}_{\kappa }$ 和 ${\stackrel{〜}{乙}}^2{\mathrm{\Sigma }}_{\text{ü}}^{\text{+}}\left(0，\mathrm{1个}，0\right)$建议将状态归因于光碎裂激发光谱中五个未分配峰的起源。由于8.46–8.80 eV的双光子能量接近8.9 eV，因此${\text{一氧化碳}}_{\text{2}}^{+}\left({\stackrel{〜}{C}}^2{\mathrm{\Sigma }}_G^{+}\right)$ 状态被Praet等人的机制解离。
