Example of a molecule

[Manoar Hossain]

Dear BGW members,

I would like to study a molecule by calculating the HOMO–LUMO gap at both the KS and GW levels, and then perform a BSE calculation to obtain the optical spectrum. I was wondering if there is a tutorial or example workflow for this type of calculation. I would greatly appreciate any guidance or references.

Thank you and best regards,
Manoar
