The approach results in a SE corrected TB framework within which the mapping of SEC of TB parameters is found to be transferable from smaller to larger systems of similar morphology, leading to a computationally inexpensive approach for the estimation of SEC in large systems with reasonably high accuracy. The scheme has been demonstrated in insulating, semiconducting, and magnetic nanoribbons of graphene and hexagonal boron nitride, where the SEC tends to strengthen the individual π bonds, leading to transfer of charges from the edge to bulk. Additionally, in magnetic bipartite systems, the SEC tends to enhance inter-sublattice spin separation. The proposed scheme thus promises to enable the estimation of SEC of bandgaps of large systems without the need to explicitly calculate the SEC of KS single particle levels, which can be computationally prohibitively expensive.Stark spectroscopy, which measures changes in the linear absorption of a sample in the presence of an external DC electric field, is a powerful experimental tool for probing the existence of charge-transfer (CT) states in photosynthetic systems. CT states often have small transition dipole moments, making them insensitive to other spectroscopic methods, but are particularly sensitive to Stark spectroscopy due to their large permanent dipole moment. In a previous study, we demonstrated a new experimental method, two-dimensional electronic Stark spectroscopy (2DESS), which combines two-dimensional electronic spectroscopy (2DES) and Stark spectroscopy. In order to understand how the presence of CT states m
