Molecular Split-Ring Resonators Based on Metal String Complexes [PDF]
J. Phys. Chem. C 118, 3766 (2014), 2014 Metal string complexes or extended metal atom chains (EMACs) belong to a family of molecules that consist of a linear chain of directly bonded metal atoms embraced helically by four multidentate organic ligands. These four organic ligands are usually made up of repeating pyridyl units, single-nitrogen-substituted heterocyclic annulenes, bridged by ...

Electric deflection of imidazole dimers and trimers in helium nanodroplets: Dipole moments, structure, and fragmentation [PDF]
Journal of Chemical Physics v.153, 081101 (2020), 2020 Deuterated imidazole (IM) molecules, dimers and trimers formed in liquid helium nanodroplets are studied by the electrostatic beam deflection method. Monitoring the deflection profile of (IM)D+ provides a direct way to establish that it is the primary product of the ionization-induced fragmentation both of (IM)2 and (IM)3.

Quantum Rate Electrodynamics and Resonant Junction Electronics of Heterocyclic Molecules [PDF]
arXiv, 2023 Quantum rate theory encompasses the electron-transfer rate constant concept of electrochemical reactions as a particular setting, besides demonstrating that the electrodynamics of these reactions obey relativistic quantum mechanical rules. The theory predicts a frequency $\nu = E/h$ for electron-transfer reactions, in which $E = e^2/C_q$ is the energy ...
