Insights from spectroscopic experiments led to the development of quantum mechanics as
the common theoretical framework for describing the physical and chemical properties of …

Mendeleev's introduction of the periodic table of elements is one of the most important
milestones in the history of chemistry, as it brought order into the known chemical and …

Relativistic quantum chemistry has evolved into a fertile and large field and is now becoming
an integrated part of mainstream chemistry. Yet, given the much-involved physics and …

The development of relativistic coupled‐cluster (CC) and equation‐of‐motion coupled‐
cluster (EOM‐CC) methods is reviewed. An emphasis is placed on recent efforts to improve …

We report the implementation of effective quantum electrodynamics (QED) potentials for all-
electron four-component relativistic molecular calculations using the DIRAC code. The …

One of the most important properties influencing the chemical behavior of an element is the
electron affinity (EA). Among the remaining elements with unknown EA is astatine, where …

It is now well established that the relativistic effects strongly influence the properties of the
heavier elements, specially the heavier elements of d-and f-block and also the heavier main …

During the last decade, six new superheavy elements were added into the seventh period of
the periodic table, with the approval of their names and symbols. This milestone was …

We review the progress in atomic structure theory with a focus on superheavy elements and
their predicted ground state configurations important for an element's placement in the …

The need for accurate calculations on atoms and diatomic molecules is motivated by the
opportunities and challenges of such studies. The most commonly used approach for all …
