Lecture 29 Introduction to Fluorescence Spectroscopy
web.iitd.ac.inIntroduction to Fluorescence Spectroscopy . When a molecule absorbs light, an electron is promoted to a higher excited state (generally a singlet state, but may also be a triplet state). The excited state can get depopulated in several ways. Introduction
An Introduction to Fluorescence Polarization - Polito
calvino.polito.itThe theory of Fluorescence Polarization, first described in 1926 by Perrin, is based on the observation that fluorescent molecules in solution, excited with plane-polarized light, will emit light back into a fixed plane (i.e. the light remains polarized) if the molecules remain stationary during the
