Several sources of errors leading to distortions in time-resolved step-scan Fourier transform infrared (FT-IR) measurements are described, and their effect on difference spectra and time traces is discussed. Fluctuations of the movable interferometer

The implementation of a sample changing wheel in combination with a step-scan FTIR spectrometer is described. This device allows collecting and averaging time-resolved data of ten samples, which can be placed successively into the infrared beam. The

The D96N mutant of bacteriorhodopsin has often been taken as a model system to study the M intermediate of the wild type photocycle due to the long life time of the corresponding intermediate of the mutant. Using time-resolved step-scan FTIR spectros

Using time-resolved step-scan FTIR spectroscopy, it has become possible to identify two different M states in the 5 to 300 μs time range, which clearly differ from the MN state. The identification has become possible by measuring a pure BR→KL diff

Replacing the chromophore of bacteriorhodopsin with chemically modified retinal analogs which cannot isomerize, allows to measure directly side effects from the laser pulse used for sample excitation in step-scan FT-IR measurements. Comparison with s

Context: Active Galactic Nuclei are highly variable emitters of electromagnetic waves from the radio to the gamma-ray regime. This variability may be periodic, which in turn could be the signature of a binary black hole. Systems of black holes are st

The molecular changes during the photoreaction of halorhodopsin from Natronobacterium pharaonis have been monitored by low-temperature static and by time-resolved step-scan Fourier transform infrared difference spectroscopy. In the low-temperature L

In this report, from time-resolved step-scan Fourier transform infrared investigations from 15 ns to 160 ms, we provide evidence for the subsequent rise of three different M states that differ in their structures. The first state rises with approxima

Our improved step-scan FTIR instrument, capable of measuring spectra within 15 ns after the flash, is employed to measure flash-induced infrared difference spectra of bacteriorhodopsin, halorhodopsin and CO-myoglobin. For all three systems it is nece
