time-resolved infrared spectroscopy
Assay MethodTime-resolved infrared spectroscopy, also termed transient infrared spectroscopy, is a light-triggered functional assay that monitors vibrational and structural dynamics of LOV photoreceptors on picosecond-to-microsecond timescales. In the cited studies, it resolved FMN triplet-state progression to cysteinyl-FMN adduct formation and subsequent protein conformational changes, including Jα helix unfolding.
