This is certainly not because there are not important questions to be answered. The area of interactions between molecules or parts of the same molecule, and rotational barriers in polymer molecules, could

Such studies differ from those applicable to small molecules through the necessity of choosing methods which do not outstrip our computing capacities, and differ from conventional infinite-crystal studies through a lack of exploitable translational symmetry.

Various semi-empirical and first-principles methods well known in quantum chemistry have been applied with considerable success to ever larger and more complex molecules, including some of biological importance, as well as to selected solid state problems involving localized electronic
