Step-scan time-resolved infrared spectroscopy
網頁2002年2月26日 · Furthermore, using time-resolved (5 micros resolution) step-scan FTIR spectroscopy at room temperature, we observe the same spectroscopic perturbation in both cytochromes aa(3) and bo(3). In addition, we observe evidence for perturbation of a second carboxylic acid side chain, at higher frequency in both enzymes at room … 網頁Step-scan FT-IR difference spectroscopy with 100-ns time resolution is applied to the membrane protein bacteriorhodopsin. The experimetal setup and data acquisition are described in great detail. The IR absorbance changes accompanying bacteriorhodopsin's photocycle are presented in a three-dimensional representation.

The first state rises with ∼3μs to only a small percentage. Its structure as judged from amide I/II bands differs in small but well-defined aspects from the …
網頁2024年10月1日 · The time resolution achievable by step-scan FTIR spectroscopy is essentially limited by the sampling frequency of the detector and can easily reach some tens of microseconds. Time resolution as high as 2 ns is possible, although at the expense of losing dynamic range [ 11 ]. 網頁Time-resolved step-scan Fourier transform infrared (FT-IR) spectroscopy has been shown to be invaluable for studying excited-state structures and dynamics in both biological and inorganic systems. Despite the established utility of this method, technical challenges continue to limit the data quality and more wide ranging applications.
