Chemical bonding is an important subject in chemistry. Thus far, the key concepts of chemical bonding have been explored using time-independent orbital models. Molecular orbital theory, valence bond theory and Woodward-Hoffmann rules are a few examples. However, dynamically how orbitals interact and form a chemical bond or in other words, how a time-dependent change of electron density manifests change of chemical bonding has not been explored, so far. For the last 10 years, my research has focused on this dynamical viewpoint of chemical bonding through a newly developed program called attosecond chemical bonding.

The first part of my talk will revolve around introducing the subject from both theoretical and experimental viewpoints. Later, I will highlight some unique self-realizations of Indian chemical education, and conclude with certain work-plans pertaining to chemical education.
