文獻(xiàn)中頻率不能重復(fù)
|
| 文獻(xiàn)中用Gamess/mp2計(jì)算,我用實(shí)驗(yàn)室Gaussian/MP2,所用基組與文獻(xiàn)中一樣,但是其中頻率重復(fù)不了,求高人指教。 |

The gold atom was treated with 19 explicit electrons using the (SBKJC) 85 effective core potential (ECP) with scalar relativistic corrections augmented with a 3f/2g set of polarization functions with f function exponents of 2.00, 0.84 and 0.31, and g function exponents of 1.90 and 0.69, and one set of s and p diffuse functions with exponents of 0.01. Spherical Gaussian functions were used. 這個(gè)里面Au的基組是怎樣定義的? |

首先非常感謝您的回復(fù)。因?yàn)槲椰F(xiàn)在做的是要解釋頻移順序,所以必須要算到正確的順序,才行。文中用到的基組是這樣自定義的: The gold atom was treated with 19 explicit electrons using the (SBKJC) 85 effective core potential (ECP) with scalar relativistic corrections augmented with a 3f/2g set of polarization functions with f function exponents of 2.00, 0.84 and 0.31, and g function exponents of 1.90 and 0.69, and one set of s and p diffuse functions with exponents of 0.01.

不好意思,我貼錯(cuò)了。應(yīng)該是: **** AU 0 AU-ECP 4 60 g-ul potential 1 1 4.3876300 -10.7235800 s-ul potential 3 0 1.5563600 6.3561200 2 3.7159300 -364.4403900 2 4.0679200 428.1975300 p-ul potential 3 0 1.1879800 4.4151800 2 3.0155100 -136.5755000 2 3.5958800 194.2053500 d-ul potential 2 0 35.2500000 8.8819800 2 5.0230700 86.7661200 f-ul potential 1 0 1.6888100 6.2160300 您能幫我看看我用的基組自定義,對了嗎? 另外,您對簡諧振動頻率和非簡諧振動頻率了解嗎,可否介紹一下資料?我對這塊不是太懂 |
