Ab Initio Studies of Radicals HBX(X=H,F, Cl,Br): Molecular Structure,Vibrational Frequencies and Potential Energy

We describe high-level ab initio calculations on the BH_2, HBF, HBCl and HBBr radicals. Molecular structure,vibrational frequencies and potential energy curves of the ground state and the first excited state, which are two Renner-Teller components for a~2Π state at linearity, are studied using the basis sets aug-cc-pVTZ and icMRCI+Q technique. On the basis of the potential energy curves, a reliable potential energy barrier to dissociation HB+X(X=F, Cl, Br) fragments and to linearity are given. The ab initio results will add some understanding on the spectrum and the photo-dissociation dynamics of the series of radicals.     

课程思政理念融入高校物理教学的实践探析——以“角动量守恒”为例

课程思政理念融入物理教学是高校实现“三全育人”要求的重要途径,可以培养学生科学的思维方式和严谨的科学认知态度,全面提升学生科学素养.以大学物理课程中“角动量守恒”一节为例,详细介绍了教学设计思路和在物理教学中如何融入思政育人元素,实现课程育人与思政育人的协同作用.
