EPJ D Colloquium - Two-dimensional laser-induced fluorescence in the gas phase: a spectroscopic tool for studying molecular spectroscopy and dynamics

Two-dimensional laser-induced fluorescence (2D-LIF) extends the usual laser-induced fluorescence technique by incorporating a second dimension, namely the wavelengths at which the excited molecules emit, thereby significantly enhancing the information that can be extracted. It allows overlapping absorption features, whether they arise from within the same molecule or from different molecules in a mixture, to be associated with their appropriate "parent" state and/or molecule.

While the first gas phase version of the technique was published a decade ago, the technique is still in its infancy, having been exploited by only a few groups to date. However, its potential in gas phase spectroscopy and dynamics is significant.

In this EPJ D article, Jason Gascooke and Warren Lawrance provide an overview of the technique and illustrate its potential with examples, with a focus on those utilising high resolution in the dispersed fluorescence dimension.
