Linear conjugated system

NettetWe present the linear response function of bond-orders (LRF-BO) based on a real space integration scheme for molecular systems. As in the case of the LRF of density, the LRF-BO is defined as the response of the bond order of the molecule for the virtual perturbation. Our calculations show that the LRF-BO enables us not only to detect inductive and … NettetWelcome to "AK Organic"This video explained Linear (Extended) and Cross Conjugation (Linear and Cross Conjugated systems) and their stability.Our Channel pro...
