聚丙烯酸长链酯的Huggins常数与其分子量的依赖性关系

聚丙烯酸高碳醇酯(PBA)及聚丙烯酸十八醇酯(POA)是具有长烷基侧链的梳状聚合物,在溶剂苯中的Huggins常数(k′)随其分子量(M)的变化而变化.在PBA-苯体系中发现,当M低于某一临界分子量(MLC)时,k′随分子量的降低显著增大;当M大于某临界分子量(MHC)时,k′随分子量的升高而增大;当M在MLC～MHC时,k′基本上保持不变.而在POA-苯体系中发现,当M低于某一临界分子量(MC)时,k′随分子量的降低显著增大;当M大于该临界分子量(MC)时,k′在0.33～0.43变化.文中同时给出了精确算法用来计算PBA-苯体系及POA-苯体系中PBA及POA的特性粘度.当k′＞0.758时,用稀释外推法计算;当0.758＞k′＞0.426时,用一点法公式[η]=ηsp/C(√)ηr计算;当0.426＞k′＞0.334时,用另一一点法公式[η]=(√)2(ηsp-lnηr)/C计算.

高剥离类镁等电子序列的磁偶极M1和电四极E2光谱跃迁理论研究

利用全相对论性多组态Dirac-Fock广义平均能级方法，系统地计算了类镁离子3s3p磁偶极Ml^3P2--^3P1和电四极E2 ^2P2--^3P0(Z=20-103)光谱跃迁的能级间隔、跃迁几率和振子强度。计算中考虑了原子核的有限体积效应，进行了高阶Breit修正和QED修正，所得到的能级间隔和最近的实验数据及理论计算值进行了比较。计算结果表明：高原子序数的高荷电离子的磁偶极矩M1和电四极矩E2跃迁几率和中性原子的电偶极E1的相当，在ICF和MCF高温激光等离子体中，磁偶极矩M1和电四极矩E2跃迁过程不容被忽视。

Ab initio calculations of accurate dissociation energy and analytic potential energy function for the second excited state B1∏ of 7LiH

The reasonable dissociation limit of the second excited singlet state B¹∏ of ⁷LiH molecule is obtained. The accurate dissociation energy and equilibrium geometry of the B¹\Pi state are calculated using a symmetry-adapted-cluster configuration--interaction method in full active space. The whole potential energy curve for the B¹∏ state is obtained over the internuclear distance ranging from about 0.10nm to 0.54nm, and has a least-square fit to the analytic Murrell--Sorbie function form. The vertical excitation energy is calculated from the ground state to the B¹∏ state and compared with previous theoretical results. The equilibrium internuclear distance obtained by geometry optimization is found to be quite different from that obtained by single-point energy scanning under the same calculation condition. Based on the analytic potential energy function, the harmonic frequency value of the B¹∏ state is estimated. A comparison of the theoretical calculations of dissociation energies, equilibrium interatomic distances and the analytic potential energy function with those obtained by previous theoretical results clearly shows that the present work is more comprehensive and in better agreement with experiments than previous theories, thus it is an improvement on previous theories.
