Requests for cell designs, circuit designs and the like have prompted us to reveal the “how we do it” aspects of several useful spectroscopic techniques that we have borrowed and refined. We have applied infrared spectroelectrochemical techniques to the study of solid state organic semiconductor materials. Cells, electrode construction and recent results will be discussed. More recently we have developed attenuated total reflectance spectroscopy techniques for determining the Uv-vis spectra of highly absorbing solid state materials and optically dense solutions (for example blood). These spectra are comparable in quality to dilute solution spectra. Finally, we will discuss how $50 worth of FETs, ICs, resistors and a commercially available 405 nm LED ($1.00 each) can replace your multi $$$$ laser. The pulsed LED allows one to make 10 nanosecond emission lifetime measurements on luminescent crystals or microliter volumes of solutions via fiber optic coupling.
