  1. Home Work 现代科学中的化学键能及其广泛应用 罗渝然(Yu-Ran Luo) luo971@ustc.edu.cn http://staff.ustc.edu.cn/~luo971

  2. Home work (1) 1. 2005年, 莫宇翔小组利用离子速度成像法测量 Do(FF) = 1.6060.001 eV Do(F+F) = 3.3340.001 eV 请你推算出D298(FF)和D298(F+F)分别是多少 kJ/mol? 2. 从手册查到, F2分子的光谱常数e = 916.64 cm-1 请你能估算出F2分子的零点能及De(F-F). Send your answer by e-mail

  3. Home work (2) Please review a short paper. 引用科学数据，不可粗心  谈谈Lange 化学手册和CRC化学和物理手册的对比 阅读: 2010LUO-Care Send your answer by e-mail.

  4. Home work (3) 请思考和回答, 为什么我们不讨论“平均键能”? 阅读: 2010LUO-Ave Send your answer by e-mail 你可以检索”百度”网, 键能, 键离解能 绝大部分是过时或错误的! 对比:2010-BDE-Tables

  5. Home work (4) 假如你在测量时, 键离解反应的实验平衡常数K的不确定性是100%. 请回答相应的键能不确定性是多少? Send your answer by e-mail

  6. Home work (5) 用质谱法测量键能时, 我们常有 BDE(R-H) = 大量 - 小量 如果该大量的偏差是2 kcal/mol, 而小量的偏差为0.5 kcal/mol. 请估算最后获得的键能偏差是多少?

  7. Home work (6) 请利用文献2008LUO(b)中推测的液体碳蒸发热数值, 再按照Gibbs理论, 进一步预测, 为什么我们不能在常见的条件下观测到液体碳.
