Well after seeing Lenard Suskinds lectures on quantum mechanics at youtube all books seems less less interesting.Also at youtube great teacher prof Balakhrishnan lectures on quantum physics are really profound introductionary course.

Well Landau Quantum mechanics is maby not introductionary course,but deffinetly something that have to be seen.Mesiah Quantum mechanics with its two levels maby is the best thing.Herbut Quantum mechanics cover all aspects with group theory applications,but not sure if english version is avaliable.

Thanks for the answer.I am interested if there are some articles published in recent scientifical physical journals about structure of C2H4,especialy by use of group symmetry.I found only works of Mulican from 1933. year and lennard Jones from 1950. year.

I need to determine possible sigma and pi orbitales of C2H4 molecul using theory of group representations and symetry.It is asked to take from C atom all orbitales with n=2. I think it could be D2h group of symetry,bu it doesn,t have 2dimensional ireducibile representations that a...
