I'm reading a terrific review by Dudley Herschbach. In the introduction he mentions, that one of the reasons to establish the Journal of Chemical Physics in 1933 was the impossibility to publish any pure theory in the Journal of Physical Chemistry by that time. This remained the case for another two decades or so, unless plenty of acknowledged theoretical results emerged.
Nowadays pure theory is almost never published in science magazines, such as Nature or Science. We definitely need to found another one.
