Odd
Hassel (17 May 1897 – 11 May 1981) was a Norwegian chemist who won the
Nobel Prize in Chemistry in 1969 for his ground-breaking research on the
structure of molecules
After completing his education, he worked
as a research assistant at the University of Oslo. He later became an
associate professor of physical chemistry at the same institution in
1925. In the 1930s, he began his ground-breaking research on the
three-dimensional structure of molecules, which would later earn him the
Nobel Prize.
His research involved the use of X-ray
crystallography to determine the structure of organic molecules. He
discovered that molecules with non-planar structures are more stable
than those with planar structures. This discovery became known as the
“Hassel Effect” and was a major breakthrough in the field of chemistry.
Hassel
also made significant contributions to the study of dipole moments in
molecules. His work led to the development of the Hassel-Bjerrum theory,
which explains the relationship between the dipole moment of a molecule
and its chemical structure.
He continued to work as a professor
of physical chemistry at the University of Oslo until his retirement in
1964. He remained active in the scientific community, however, and
continued to publish research papers throughout his lifetime.
