dissociation energy與binding energy 已有2人參與

Atkins的《物理化學》給出:dissociation energy(De)=potential well depth(D0)+ZPE Wolfgang的《Atoms,Molecules and Photons》給出:dissociation energy(De)+ZPE=Binding energy 所以D0是binding energy,De是dissociation energy這應該是沒有問題的。 但審稿人卻說”The quantity D_e in Eq. (3) is not "the dissociation energy" but the well depth or the electronic binding energy. The dissociation energy, a measurable property denoted usually by , is equal to D_e minus the zero-point energy. D_0 depends on the nuclear masses, D_e does not. “ Eq. (3)是Murrell-Sorbie (M-S) potential energy function:y=-De(1+a1(x-Re)+a2(x-Re)^2+a3(x-Re)^3)*exp(-a1(x-Re)) 他應該也是承認De=D0+ZPE,但是卻說D_e是well depth or the electronic binding energy,而D_0才是dissociation energy 請教這應該怎樣回復? |

dissociation energy(De)=potential well depth(D0)+ZPE y=-De(1+a1(x-Re)+a2(x-Re)^2+a3(x-Re)^3)*exp(-a1(x-Re)) 關(guān)鍵在于兩條式中的 De 是否為同一個東西,如果第二式里的 De 就是第一式中的 D0 呢? “所以D0是binding energy,De是dissociation energy這應該是沒有問題的! 并不是每本書都這樣定義的,我經(jīng)?吹絛issociation energy叫D0的。 |
