The Schrodinger equation and models of chemistry

The Schrodinger equation and its elements As early as 1929, the noted physicist P. A. M. Dirac wrote1 

The underlying physical laws necessary for the mathematical theory of a largepart of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. 

A similar view was echoed in a 1944 textbook of quantum chemistry 2 

In so far as quantum mechanics is correct, chemical questions are problems in applied 

The implication is that chemical phenomena are determined by the laws of quantum mechanics, as expressed in the fundamental time-independent Schrodinger equation
