The emission spectroscopy of C2 produced in a hydrocarbon/oxygen flame: An APCELL experiment

Abstract

The experiment develops practical skills related to the underlying principles of atomic and molecular spectroscopy that is presented in most second and third year lecture courses and extends the application of these principles to combustion chemistry. Students should have a basic knowledge of quantised energy levels in atoms (electronic) and molecules (rotational, vibrational and electronic). Ideally, students should also have an understanding of the spectroscopic concepts of transitions between these levels and the relationship with the electromagnetic spectrum. However, this is not considered essential as students can learn these concepts as part of the experiment.
