[Octopus-users] Negative absorption co-efficient in TD run

[Juzar Thingna]

Hello Everyone,
I'm performing some TD calculations but when I plot the absorption spectra
from the TD run I get negative values of the absorption co-efficient. Please
can someone explain to me, why this is happening?

Regards,
Juzar
