Abstract
Imaging Raman spectroscopy is explored as a new tool for in situ studies of electrochemical systems. The technique provides a spatially resolved view of molecular species present along a focused laser line. The capabilities of our system are demonstrated using an electrodeposited thin film of plated on a cylindrical platinum electrode. It is shown that line‐imaging Raman spectroscopy is able to measure the properties of the thin film deposit while simultaneously monitoring the concentration of solution species within ≈1 mm of the surface. The Raman image presented here has a spatial resolution of ≈6 μm and a spectral resolution of 24 cm−1, though neither constitutes resolution limits of the instrument.
