What is principle of fluorescence? Fluorescence describes a phenomenon where light is emitted by an atom or molecule that has absorbed light or electromagnetic radiation from another source. In absorption, high energy light excites the system, promoting electrons within the molecule to transition from the ground state, to an excited state.
What is the basic principle of fluorescence spectroscopy? Fluorescence spectroscopy analyzes fluorescence from a molecule based on its fluorescent properties. Fluorescence is a type of luminescence caused by photons exciting a molecule, raising it to an electronic excited state.
What is mechanism of fluorescence? When the electrons relax to their ground state or another state with a lower energy level, energy is released as a photon. As some of the energy is lost during this process, light with an increased wavelength and lower energy is emitted by the fluorochrome compared to the absorbed light.
What is the principle of Spectrofluorometer? Fluorescence spectroscopy is a type of electromagnetic spectroscopy which analyzes fluorescent molecules. It exploits the phenomenon of electron excitation upon collision with high energy particles like photons and other excited electrons.

What does the principle of base pairing demonstrate?
The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (called Chargaff’s rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.

What is the operating principle of a defibrillator?
Most defibrillators are energy-based, meaning that the devices charge a capacitor to a selected voltage and then deliver a prespecified amount of energy in joules. The amount of energy that arrives at the myocardium is dependent upon the selected voltage and the transthoracic impedance (which varies by patient).
