Ultrafast spectroscopic studies of the photophysics of phenyl- substituted butadienes in liquids.

摘要

The transient absorption decay times of tetraphenylbutadiene (TPB) and tetraphenylmethylbutadiene (TPMB) are measured as a function of solvent viscosity and of probe wavelength. The TPB spectra suggest that after excitation, TPB relaxes to the bottom of t ...
