Re^5: How to get the excited state properties printed in TDDFT output?

Dear Alex,
Here is more information about the situation I discussed in my previous post. I get the following information in the ascending order of LINE NUMBER:

1) Line number 63289::"TOTAL MULLIKEN AND LOWDIN ATOMIC POPULATIONS"  appears.  Before this line, there is NO mention of relaxed or unrelaxed words.
2) Line number 63999:: "properties for unrelaxed density" appears.
3) Line number 65801:: "TOTAL MULLIKEN AND LOWDIN ATOMIC POPULATIONS"  appears.
4) Line number 66501::"properties for relaxed density" appears.
5) Line number 67833:: "TOTAL MULLIKEN AND LOWDIN ATOMIC POPULATIONS"  appears.

I would be glad if you could tell me which STATES these properties belong to? I feel that the 1) and 2) are for unrelaxed ground and first excited state.. And 5) is for RELAXED first excited state... Also where do I find Lowdin data for relaxed ground state?
But the confusion also arises due to MaSK software, which picks up the 1) for plotting. Could you suggest me any other software for plotting the Lowdin charges for the relaxed ground and first excited state?

Kind Regards,

>Thanks for the information. I have run the program using the same. I have another doubt now. I used "MaSK" for plotting the LOWDIN charges. I noticed that it plotted the data under section "TOTAL MULLIKEN AND LOWDIN ATOMIC POPULATIONS" which appeared first time in the o/p file. Is it correct?
>Because "TOTAL MULLIKEN AND LOWDIN ATOMIC POPULATIONS" appears many times in the o/p file and also the ONE that appears LAST in file ACTUALLY is for RELAXED DENSITY.. SO which data should I use?
