Thecaa3-oxidase from Thermus thermophilushas been studied with a combined electrochemical, UV/VIS and Fourier-transform infrared (FT-IR) spectroscopic approach. In this oxidase the electron donor, cytochromec, is covalently bound to subunit II of the cytochrome c oxidase. Oxidative electrochemical redox titrations in the visible spectral range yielded a midpoint potential of )0.01 ± 0.01 V (vs. Ag/AgCl/3MKCl, 0.218 V vs. SHE¢) for the hemec.

Short-Time Fourier Analysis A fundamental problem in signal analysis is to find the spectral components containedin a measuredsignal z ( t ) and/or to provide information about the time intervals when certain frequencies occur. An example of what we are looking for is a sheet of music, which clearly assigns time to frequency, see Figure 7.1. The classical Fourier analysis only partly solves the problem, because it does not allow an assignment of spectralcomponents to time. Therefore one seeks other transforms which give insight into signal properties in a different way. ...
