Transient absorption spectroscopy: A pump–probe technique that monitors the change in absorption of a sample following an initial excitation, capturing ultrafast dynamical processes.

Here we report transient absorption spectroscopy measurements on CdS and CdSe nanorods recorded at temperatures ranging from 160 to 294 K. We find that the exponent of the power law is ...

A visible-pump/UV-probe transient absorption is used to characterize the ultrafast dynamics of bacteriorhodopsin with 80-fs time resolution. We identify three spectral components in the 265-to 310-nm ...
