The photodissociation dynamics of furan at 800 nm was studied using velocity map imaging technology coupled with time-of-flight mass spectrometry. Dissociation channels are obtained by analysis of furan multiphoton ionization dissociation under strong field. According to time-of-flight mass spectrometry experiments, C₄H₄O⁺, C₃H₃⁺, C₃H₄⁺, C₂H₂O⁺, HCO⁺ are obtained by multiphoton ionization dissociation of furan. By calculating the speed distribution and kinetic energy distribution using velocity map imaging technology, it can be seen that there are two channels of high energy channel and low energy channel in the process of photodissociation. The anisotropy parameters of furan dissociation for both channels are close to 0 (isomorphism) by analysis of the angular distribution of dissociated fragment ions. The density functional theory was employed to calculate the configuration change of the furan molecule before and after ionization, the energy level intensity of the ionic states and corresponding oscillator strength.

使用速度图成像技术结合飞行时间质谱仪研究了呋喃在800 nm处的光解动力学。通过分析强磁场下的呋喃多光子电离解离获得解离通道。根据飞行时间质谱实验，C ₄ H ₄ O ⁺，C ₃ H ₃ ⁺，C ₃ H ₄ ⁺，C ₂ H ₂ O ⁺，HCO ⁺通过呋喃的多光子电离解离获得。通过使用速度图成像技术计算速度分布和动能分布，可以看出光解离过程中存在高能通道和低能通道两个通道。通过分析解离的碎片离子的角度分布，两个通道的呋喃解离的各向异性参数都接近于0（同构）。利用密度泛函理论计算了呋喃分子在电离前后的构型变化，离子态的能级强度和相应的振子强度。
