Re^4: Unable to understand the TDDFT obtained spectra..(SOLVED)

Dear Pavlo,
As discussed with you, I used Gabedit for obtaining the uv spectra. It shows the spectra very well. But when I save its ASCII file, I am unable to open it in the QTIPLOT (due to a single space). I need the data in two column form which could directly be imported into Qtiplot. Any suggestions?

Regards,
