WebApr 10, 2024 · Quantum chemical modeling using scalar relativistic and SO DFT on cluster models shows that the NHD is driven by the SO term of the magnetic shielding. Consistent with SO heavy atom effects on NMR chemical shifts, the NHD can be explained in terms of the frontier molecular orbitals and the involvement of Sn and X atomic orbitals in Sn–X … WebFeb 20, 2024 · Dear Walter, I forgot to reference my answer: "This is the DTFT, the procedure that changes a discrete aperiodic signal in the time domain into a frequency domain that is a continuous curve. In mathematical terms, a system's frequency response is found by taking the DTFT of its impulse response. Since this cannot be done in a …
