"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.
