A Raman Spectroscopic and Electrochemical Study of the Photoinduced Crystallization of Triethylenediamine Triiodide upon a Silver Electrode

Abstract

When a silver electrode, electrochemically coated with AgI, is immersed in an electrolyte containing NaI and the diprotonated form of 1,4- diazabicyclo2.2.2octane (abbreviated DABCO-H22+), and is bathed in 514.5 nm radiation from an argon ion laser through the objective of the microscope attachment of the DILOR Omars-89 Raman spectrophotometer, crystals form from the focal point. These are attributed to DABCO-h22+ 213-. Both spectroscopic and electrochemical experiments are described and interrelated. A mechanism for this photoinduced electrochemical crystal growth is presented.
