Note that both CH3 and NH2 have 5 alpha and 4 beta electrons, while CH3NH2 has 9 alpha and 9 beta electrons. Evidently, the total numbers of alpha and beta electrons in the two fragments, namely 5+5 and 4+4, does not match the ones of the complex. So, we must flip electron spin of one fragment (either CH3 or NH2). In this example, we will flip electron spin of NH2, i.e. exchanging all information of its alpha and beta electrons.

请教大家,我在看文献时有这么一句,Basis sets of quadruple-zeta quality were applied for the 4s, 4p, 4d, and 5s electrons of Ru and Mo,里面的quadruple-zeta quality是什么意思?我在自己的Gaussview中怎么没有找到?
