Abstract

This paper re-evaluates the formative year of quantum mechanics-from Heisenberg's first paper on matrix mechanics to Schr & ouml;dinger's equivalence proof-by focusing on the role of radiation in the emerging theory. We argue that the radiation problem played a key role in early quantum mechanics, a role that has not been taken into account in the standard histories. Radiation was perceived by the main protagonists of matrix and wave mechanics as a central lacuna in these emerging theories and continued to contribute to the theoretical development and conceptual clarification of quantum mechanics. Studying the interplay between quantum mechanics and radiation, the paper provides an account of (a) how quantum mechanics was able to connect to its empirical basis in spectroscopy and (b) how Schr & ouml;dinger's equivalence proof emerged from his explorative calculations on the emission of radiation.
