Electronic resonances are states that are unstable towards loss of electrons. They play
critical roles in high-energy environments across chemistry, physics, and biology but are …

Tailored coupled cluster theory represents a computationally inexpensive way to describe
static and dynamical electron correlation effects. In this work, we scrutinize the performance …

Upon ionization of an atom or a molecule, another electron (or more) can be simultaneously
excited. These concurrently generated states are called “satellites”(or shakeup transitions) …

Despite the long history of spectroscopic studies of the C2 molecule, fundamental questions
about its chemical bonding are still being hotly debated. The complex electronic structure of …

A prerequisite for laser cooling a molecular anion, which has not been achieved so far, is the
precise knowledge of the relevant transition frequencies in the cooling scheme. To …

The molecular anion C 2− is currently of interest as a candidate for laser cooling due to its
electronic structure and favorable branching ratios to the ground electronic and vibrational …

The electronic structure of four prototypical Cvetanović diradicals, species derived by
addition of O (3P) to unsaturated compounds, is investigated by high-level electronic …

Coupled cluster Green's function (CCGF) approach has drawn much attention in recent
years for targeting the molecular and material electronic structure problems from a many …

Atomic and molecular resonances play an important role in many physical processes, hence
developing theoretical tools to properly calculate these states is required. Recently, we …

Calcium dicarbide, CaC 2, has been characterized at high resolution in the laboratory, and
its main isotopologue, 40 CaC 2, has been assigned to 14 rotational emission lines between …
