Excitation of extra-electron is caused by the energy released in ATP hydrolysis in protein molecules. The excitation can self-trap as a soliton through interaction with deformation of amino acids. When donors and acceptors are distributed along the protein molecular chains close enough, the electrons in the donors can be transferred by the soliton due to the interaction between them. Authors calculate the speed and kinetic coefficient of the electron transfer from the donors and acceptors in the molecular chains with cubic anharmonicity by non-equilibrium statistical theory. Some interesting results are obtained.
额外电子的激发是由蛋白质分子中ATP水解释放的能量引起的。通过与氨基酸变形的相互作用,激发能以孤子的形式自陷。当供体和受体沿蛋白质分子链分布得足够近时,由于它们之间的相互作用,供体中的电子可以通过孤子转移。用非平衡统计理论计算了具有三次非调和性的分子链中电子从给体和受体转移的速度和动力学系数。得到了一些有趣的结果。

The photoionization of methanol seeded in He, N2, Ar gases by an inten se 25ns NdYAG 532nm laser has been studied by timeofflight mass spectrome try . At the laser intensity about 1011W·cm-2, strong multicharged io ns Cq+(q=2—4) and Oq+(q=2—4) appeared in the mass spectra apart from the ions coming from multiphoton ionization (MPI) process when Ar w as used as a carrier gas. From the simulation, we can find the vel ocity of multicharged ions is distributed in Gaussian shape with a FWHM of 6 4×104 m/s. From the experimental results of changing carrier gases and changi ng the delay time of the pulsed electric field, the conclusion can be drawn that th ose multicharged ions come from the Coulomb explosion of methanol cluster ions .
用飞行时间谱法研究了25ns Nd YAG 532nm强激光在He、N2、Ar气体中对甲醇的光电离作用。在激光强度约为10 11 W·cm-2时,除了多光子电离(MPI)过程产生的离子外,质谱中还出现了强的多带电离子Cq+(q= 2-4)和Oq+ (q= 2-4)。仿真结果表明,多荷电离子的速度呈高斯分布,FWHM为6º4×10º4 m/s。从改变载流子气体和改变脉冲电场延迟时间的实验结果可以得出,这些多荷离子来源于甲醇簇离子的库仑爆炸。

The potential energy function for ground state X5Σ- of the PuO molecule was worked out by the quadratic configuration interaction of single and double substitution method, based on the approximation of relativistic effective core potential for Pu atom and all-electron 6-311G* basis set for O atom. The calculated results for Re,De,Be,αe,ωe and ωeχe are 0.183nm,7.3909eV,0.3365,0.001642,781.15,and 2.77cm-1,respectively.In addition,the thermodynamic functions ΔH0,ΔS0,ΔG0 and Cp of the PuO(g) in standard state are also calculated,which are -118.88kJ/mol,96.16J/mol·K,-147.55kJ/mol,and 31.5656J/mol·K,respectively. All these results are in good agreement with the experimental data.
