請(qǐng)教gaussian計(jì)算激發(fā)態(tài)的問題
|

利用高斯中的td計(jì)算激發(fā)態(tài),我能夠得到高斯關(guān)鍵詞介紹中的這些內(nèi)容: ======================================================== Here is the key part of the output from a TD excited states calculation: Excitation energies and oscillator strengths: Excited State 1: Singlet-A2 4.0147 eV 308.83 nm f=0.0000 <S**2>=0.000 8 -> 9 0.70701 This state for optimization and/or second-order correction. Copying the excited state density for this state as the 1-particle RhoCI density. Excited State 2: Singlet-B1 9.1612 eV 135.34 nm f=0.0017 <S**2>=0.000 6 -> 9 0.70617 Excited State 3: Singlet-B2 9.5662 eV 129.61 nm f=0.1563 <S**2>=0.000 8 -> 10 0.70616 The results on each state are summarized, including the spin and spatial symmetry, the excitation energy, the oscillator strength, the S2, and (on the second line for each state) the largest coefficients in the CI expansion. The ECD results appear slightly earlier in the output as follows: 1/2[<0|r|b>*<b|rxdel|0> + (<0|rxdel|b> *<b|r|0> ) *] Rotatory Strengths (R) in cgs (10**-40 erg-esu-cm/Gauss) state XX YY ZZ R(length) R(au) 1 0.0000 0.0000 0.0000 0.0000 0.0000 2 0.0000 0.0000 0.0000 0.0000 0.0000 3 0.0000 0.0000 0.0000 0.0000 0.0000 1/2[<0|del|b>*<b|r|0> + (<0|r|b>*<b|del|0> )*] (Au) state X Y Z Dip. S. Osc.(frdel) 1 0.0000 0.0000 0.0000 0.0000 0.0000 2 -0.0050 0.0000 0.0000 0.0050 0.0033 3 0.0000 -0.2099 0.0000 0.2099 0.1399 ================================================================ 現(xiàn)在有兩個(gè)問題不明白,麻煩各位高手給指點(diǎn)一下,謝謝! 1. 上面的內(nèi)容只給出了基態(tài)到激發(fā)態(tài)的躍遷能量和振子強(qiáng)度,激發(fā)態(tài)的波函數(shù)是怎么描述的呢?我怎么能看到? 2. 最后面的1/2[<0|r|b>*<b|rxdel|0> + (<0|rxdel|b> *<b|r|0> ) *] 和 1/2[<0|del|b>*<b|r|0> + (<0|r|b>*<b|del|0> )*] (Au) 對(duì)應(yīng)的公式應(yīng)該是哪兩個(gè),里面的各項(xiàng)分別是什么物理意義呢? |
