  • Potential energy surface for the model unimolecular reaction HNC → HCN (167 citations)
  • On the cluster convergence of chemisorption energies (161 citations)

What are the main themes of his work throughout his whole career to date?

Ulf Wahlgren spends much of his time researching Atomic physics, Physical chemistry, Ab initio, Computational chemistry and Inorganic chemistry. His Atomic physics research is multidisciplinary, incorporating elements of Excitation and Atomic orbital. Ulf Wahlgren interconnects Ion, Uranyl and Hydroxide in the investigation of issues within Physical chemistry.

His study looks at the relationship between Ab initio and topics such as Ab initio quantum chemistry methods, which overlap with Atom and Ionization. His work on Electronic structure is typically connected to Theoretical chemistry as part of general Computational chemistry study, connecting several disciplines of science. The Inorganic chemistry study combines topics in areas such as Crystallography, Crystal structure, Inorganic compound and Molecule.

He most often published in these fields:

  • Atomic physics (30.25%)
  • Physical chemistry (25.31%)
  • Ab initio (24.69%)

What were the highlights of his more recent work (between 2005-2015)?

  • Uranyl (11.73%)
  • Physical chemistry (25.31%)
  • Quantum chemistry (6.17%)

In recent papers he was focusing on the following fields of study:

His primary scientific interests are in Uranyl, Physical chemistry, Quantum chemistry, Ion and Ab initio. His studies deal with areas such as Inorganic chemistry, Crystallography, Covalent bond, Excited state and Photochemistry as well as Uranyl. His Excited state study is concerned with the field of Atomic physics as a whole.

Ulf Wahlgren works in the field of Physical chemistry, namely Aqueous solution. His biological study spans a wide range of topics, including Chemical physics, Spectroscopy, Molecule and Actinide chemistry. As a part of the same scientific study, Ulf Wahlgren usually deals with the Ion, concentrating on Solvent effects and frequently concerns with Electronic structure, Computational chemistry, Configuration interaction and Solvation shell.

Between 2005 and 2015, his most popular works were:

  • Actinide Chemistry in Solution, Quantum Chemical Methods and Models (95 citations)
  • Probing the Nature of Chemical Bonding in Uranyl(VI) Complexes with Quantum Chemical Methods. (85 citations)
  • Theoretical investigation of the energies and geometries of photoexcited uranyl(VI) ion: a comparison between wave-function theory and density functional theory. (58 citations)

In his most recent research, the most cited papers focused on:

  • Quantum mechanics
  • Organic chemistry
  • Hydrogen

Ulf Wahlgren mostly deals with Uranyl, Quantum chemistry, Density functional theory, Atomic physics and Computational chemistry. In his study, which falls under the umbrella issue of Uranyl, Spectroscopy, Ab initio, Ion and Physical chemistry is strongly linked to Solvent effects. His research in Density functional theory intersects with topics in Excited state and Wave function.

The study incorporates disciplines such as Perturbation theory and Ground state in addition to Excited state. His Wave function study necessitates a more in-depth grasp of Quantum mechanics. His primary area of study in Computational chemistry is in the field of Electronic structure.
