These techniques reveal the microscopically heterogeneous distribution of species in polymer systems, which is specially pronounced in solutions of polyelectrolytes. They also allow us to study conformational mobility of flexible chains.
  7. Fluorimetry: Principle and Applications Introduction: A large number of substances are unknown which can absorb ultraviolet or visible light energy. But these substances lose excess energy through heat through collisions with neighboring atoms or molecules

Applications of fluorimetry. 1. To analyze nucleic acids like DNA and proteins. 2. It is used to measure inorganic compounds containing metals or ions like beryllium, lithium, aluminum, zinc, etc. 2. It helps to analyze organic compounds like steroids, proteins, alkaloids, etc. 3. It is also a specified method to analyze medicines like morphine. Fluorescence spectroscopy (fluorimetry or spectrofluorometry) probes both electronic and vibrational energy levels of a sample.Fluorescence is a form of luminescence, a spontaneous emission of radiation by a fluorescent molecule, fluorophore (Kokawa et al., 2015; Lichtman and Conchello, 2005).The emission takes place when an orbital electron of a fluorophore relaxes to its ground state S 0 by.
