Abstract: Two kinds of fiberoptic spectroelectrochemical probes were constructed and characterized in vitro. The first probe performed spectroscopy by transmitting light from one end of a Pt cyclinder, acting as a working electrode, to the other. The second probe had a mirror at one end of a Pt cylinder, also acting as a working electrode. A ferri/ ferrocyanide couple was used as a test system. Cyclic voltammetry at the probe was slightly distorted due to unconventional cell geometry, but otherwise normal. Electrolysis times were long, 9 minutes, despite near thin layer conditions because of a large charging current. A study of absorbance at 420 nm vs. concentration of ferricyanide indicated that absorbance spectroscopy obeys the Beer-Lambert Law.
