Bonding in Mercury-Alkali Molecules: Orbital-driven van der Waals Complexes

Bonding in Mercury-Alkali Molecules: Orbital-driven van der Waals Complexes

The bonding situation in mercury-alkali diatomics HgA ((2)Sigma(+)) (A = Li, Na, K, Rb) has been investigated employing the relativistic all-electron method Normalized Elimination of the Small Component (NESC), CCSD(T), and augmented VTZ basis sets. Although Hg,A interactions are typical of van der Waals complexes, trends in calculated D(e) values can be explained on the basis of a 3-electron 2...

Breaking van der Waals molecules with magnetic fields

Manipulating dynamics of molecules with external fields has long been a sought-after goal of experimental and theoretical research. Several groups have studied elastic and inelastic collisions of ultracold alkali atoms in the presence of Feshbach scattering resonances [1–6]. It was found that the probabilities of elastic collisions and inelastic energy transfer undergo dramatic changes near Fes...

Electrotunable artificial molecules based on van der Waals heterostructures

Quantum confinement has made it possible to detect and manipulate single-electron charge and spin states. The recent focus on two-dimensional (2D) materials has attracted significant interests on possible applications to quantum devices, including detecting and manipulating either single-electron charging behavior or spin and valley degrees of freedom. However, the most popular model systems, c...

Van Der Waals Complexes of Organomettalic Molecules: the Rotational Spectrum of Dimethylsilane Argon

Spectroscopy on triphenylamine and its van der Waals complexes

Both vibrationally and rotationally resolved spectra of the S, + So transition in jet-cooled triphenylamine (TPA) around 340320 nm are reported. Medium resolutton spectra (0.5-l .O cm-’ resolution) are recorded using ( 1 + 1 )-resonance enhanced multi photon iomzation (REMPI) with mass selective time-of-flight (TOF) detection in a pulsed molecular beam apparatus. The origin ofthe S,+ So transit...
