查询词典 transition energy

Using the dynamicalsymmetry and considering the off-diagonal term of rovibrational interaction, weobtained firstly the expression of rotational energy levels similarly to thecommonly used term value equation in spectrum analysis. By using the formula,the rotational levels of different vibrational transition for linear triatomic molecules〓, HCN, OCS,〓 and its isotope species, which are on the electronic groundstate and the first electronic excited state, were analyzed. The obtained rotationalconstants accord with the ones from other calculation methods very well.

Greenpeace USA's global warming campaign director, Steven Biel, said that Barack Obama had "reframed the conversation"."Clearly the economy is the major issue, but he knows that the solution to the economic problems lies in fixing health care, education and a transition to renewable energy," Mr Biel said."Listening to him, you get the sense that he really believes in it. Of course he's a good politician but you feel like it's from the heart."
