I haven't looked at any recent books, but the classics by Chris Cramer (Essential Computational Chemistry) and Frank Jensen (Introduction to Computational Chemistry) both come highly recommended!

Thank you, Goumans! I have Cramer's book and will consider Frank Jensen's book.

Dear Ahmad,

Yes, a gree with answers of Dr. T. P M Goumans & Dr. Mutasem Z. Bani-Fwaz .

With my best regards for all.

Thanks dear Dr. Mutasem for your valuable answer

Thank you dear Dr. Adel

Thanks dear Prof. James, your addition is very much appreciated.

I agree with all the previous suggestions

There are lots of new books, so I will not introduce them to you here. Instead, when asked to introduce only one book of quantum chemistry from a student, I always recommend quantum chemistry by Henry Eyring. This book is a very old and historical book, but it is a book that students planning to specialize in quantum chemistry wants to read once. When I entered university, I was introduced to the teacher in the first quantum chemistry lecture. Even now, since the description of the transition state theory is excellent (proposed by Henry Eyring), I often read back.

Dear, Ahmed Alrawashdeh,

I have these books, may be you like it.
