The textbook Atomic and Molecular Physics (often titled Atomic and Molecular Spectra: Laser "Atomic and Molecular Spectra: Laser" by Rajkumar Searching

how electrons and nuclei interact within a single atom, how atoms bind to form molecules, and how those entities behave under external fields and collisions

Atomic‑molecular physics occupies the conceptual bridge between the isolated‑atom world of quantum electrodynamics and the many‑body realm of condensed‑matter and chemical physics. It addresses . Planck’s constant h, ħ Speed of light c

• Planck’s constant h, ħ
• Speed of light c (in cm/s for spectroscopy)
• Rydberg constant R∞ (in cm−1)
• Reduced mass μ for diatomic molecules
• Rotational constant B = ħ^2 / (2I) or in spectroscopic units B̃ = h/(8π^2cI)

Some of the key features of the book include:

The book is divided into several chapters, each of which covers a specific topic in atomic and molecular physics. The chapters include:
