Fluorescence Spectrophotometry
The fluorescence absorption and emission spectra reflect the vibrational level structures in the ground and the excited electronic states, respectively. The Frank–Condon principle states the fact that the
Read MoreHome / Principle of Steady-State Fluorescence Spectrometer
There are two main types of fluorescence spectroscopy: steady-state and time-resolved. The extent of the applications has benefited from the development of the Green Fluorescence Protein (GFP) family that allows for the expression of fluorescent proteins in cells and tissues; a feature that allows the experimenter to follow the whereabouts of proteins in live cells and even tissues. shows the fraction of incident light absorbed by the material over a range of frequencies.
