The "rules" that govern the subatomic world.

"Introductory Quantum Chemistry" by A.K. Chandra is an excellent textbook for undergraduate students of chemistry, physics, and related fields. The book provides a solid foundation in the principles of quantum chemistry and is a valuable resource for anyone looking to gain a deeper understanding of this fascinating subject. I highly recommend it to students and instructors alike.

: The text prioritizes understanding the physical significance of quantum mechanics over purely abstract mathematical derivations.

Yes, for the chemistry paper (CY), Chandra covers 90% of the quantum section. However, for recent topics (like quantum computing in chemistry or DFT basics), you will need supplemental notes.
