<![CDATA[Re: Question on NBO analysis]]> //www.umsyar.com/wfnbbs/viewtopic.php?pid=5313#p5313 I see. Would you say it is currently not possible at all (using any software)?

There is no corresponding analysis in Multiwfn.

<![CDATA[Question on NBO analysis]]> //www.umsyar.com/wfnbbs/viewtopic.php?pid=5311#p5311 Dear all,

What I want to do is as below:

Let's say there is a complex, consisting of 2 fragments (just like the situation of CDA analysis). There would be an NBO of a certain chemical bond of interest in the structure of the fragment A, whose electron density map would be reorganized in some extent when the fragment A and B form the whole complex. What I want to do is find out which NBO's in the structure of fragment B are responsible for this NBO reorganization (as well as the nature of the interactions and the % contributions).

Would this be possible by Multiwfn? Thank you very much in advance.
