WebResultant dipole moment was defined as net dipole moment of those receptor backbone atoms which interacts with the bonded ligand. During the steered molecular dynamics (SMD) simulations, the spring constant was chosen as k = 1000 kJ/(mol·nm 2 ) ≈ 1700 pN/nm, which corresponds to the upper limit of k of cantilever used in AFM experiments. WebFeb 19, 2024 · Experimental probes of the electric dipole moment of the electron (eEDM) provide strong constraints on theories of particle physics beyond the Standard Model (BSM) [ 1 – 6 ]. The most stringent limit on an eEDM has been realized in experiments using a diatomic molecule, ThO, in a 3 Δ 1 state, limiting the eEDM to < 1.1 × 10 −29 e cm [ 7, 8 ].
