<p>what the hell are these people talking about? Physical chemistry depends heavily on the overlap between chemistry and math. particularly more theoretical. </p>
<p>Look up a thing called density functional theory (DFT). It was derived by a physicist, but the dude got the noble prize in chemistry! it allowed computers to model complex chemical molecules which is huge for chemist! im sure a drug company like pfizer would pay a lot of money for you to model a molecule before they spend weeks (and tons of chemicals) synthesizing it.
additionally, almost all forms of spectroscopy need math people to do the theory/programing. Say someone pours a bunch of chemicals into a vial and thinks they made the next big drug. how do you know what what was made? typically, a laser or some form of e&m will interact with the chemical substance, but many people need to code and do theory math to get that data onto a computer and what not. </p>
<p>esp if you are interested in theory math, signal processing for spectroscopic techniques (NMR/MRI, mass spec) can easily be a phd or research position at a university.
P.M. if you have more questions. The people above clearly dont know that much about chemistry.</p>
