What type of chemistry is this?

[Horseb0x]

The 2nd chapter in my spectroscopy course is titled quantum mechanics and at the end of it it goes on about particles in 1 dimensional boxes. What would I google to find info on this kinda thing? Quantum chemistry?

Quantum chemistry, the same approximations are used by quantum mechanics.
