<div dir="ltr"><div><div><div><div><div><div><div><div>Dear molpro users,<br><br></div>I want to do MRCISD+Q excitation energy, oscillator strengths and dipole moments calculations. Let's say that I want to do it for S0--->S1 and S0---->S2 transitions. Now, I struggle with couple of things. Firstly, how do I specify that I want to have only single and double excitations in 10x10 space (that means 10 electrons in 10 orbitals- 5 doubly occupied and 5 virtual)?<br>
Secondly, I can't find how to calculate oscillator strengths and do the Davidson correction (Q).<br></div>At last, I am not sure if my input (attached) will correctly calculate the dipole moments in all states.<br><br>
</div>I also want all of my core orbitals to be frozen. I did not specify it because it is default, right?<br><br></div><div>I have read this example:<br><a href="http://www.molpro.net/info/2012.1/examples/h2op_mrci_trans.com">http://www.molpro.net/info/2012.1/examples/h2op_mrci_trans.com</a><br>
<br></div>If I understand it correctly, the user specifies two wavefunctions between which the transition moment is calculated. But I do not really understand how to read it. But I want to calculate this transition between states which will be calculated.<br>
<br></div>I hope you will understand where my problem lies :).<br><br></div>Thank you for any advice.<br></div>Best wishes,<br></div>Dawid Grabarek<br><div><div><div><div><div><div><div><br><br></div></div></div></div></div>
