How much quantum mechanics are in quantum chemistry?

Click For Summary
SUMMARY

The discussion centers on the necessity of taking quantum physics after completing two semesters of physical chemistry for chemistry majors. It concludes that while quantum chemistry is a separate required course, it does not delve as deeply into quantum mechanics as physics courses do. The primary distinction lies in the types of approximations and problem symmetries relevant to chemistry. Macquarrie's quantum chemistry text is recommended as a solid introduction to quantum mechanics concepts applicable in chemistry.

PREREQUISITES
  • Understanding of physical chemistry concepts, particularly thermodynamics and liquid/vapor equilibrium.
  • Familiarity with basic quantum mechanics principles.
  • Knowledge of quantum chemistry as a distinct field from quantum physics.
  • Ability to apply approximations and symmetry considerations in chemical problems.
NEXT STEPS
  • Study Macquarrie's quantum chemistry text for foundational concepts in quantum mechanics.
  • Explore the differences between quantum chemistry and quantum physics in detail.
  • Research specific quantum mechanics applications in chemical systems.
  • Investigate advanced topics in quantum chemistry, such as computational methods and molecular modeling.
USEFUL FOR

Chemistry majors, physics enthusiasts, and students interested in the intersection of quantum mechanics and chemistry will benefit from this discussion.

So I am a chemistry major, but really like math and physics as well. I was wondering how necessary it would be to take quantum physics after taking two semesters of physical chemistry. I go to a small school and there aren't a host of physics classes, so quantum physics is the end of its road and isn't a prerequisite for any other classes, but I was wondering if it would even be worth taking after two semesters of physical chemistry. Thanks in advance.
 
Physics news on Phys.org
Depends on what is in the physical chemistry. I have seen physical chemistry courses that were heavy on thermodynamics, liquid/vapor equilibrium, things like viscosity, surface tension and so on, with no mentioning of quantum mechanics. Quantum chemistry was offered as a separate, required course.
 
It's nowhere near the level that the physicists do it, but as a chemists, we don't need that deep of an understanding for most of our work unless you're a theorist.
 
What do you want to do? The topics covered in a quantum chemistry or physical course generally diverge fairly quickly from a pure quantum mechanics class.
 
The basics of quantum mechanics are the same in chemistry and physics. There are very few exact solutions beyond a few simple systems like the harmonic oscillator and the hydrogen atom. So the difference between quantum chemistry and quantum physics is basically the sorts of approximations which are useful, how much symmetry there is in a problem etc. So eg. Macquarrie's quantum chemistry text is a perfectly good introduction to quantum mechanics.
