Spectroscopy/Electronic spectroscopy

Electronic Spectroscopy is concerned with the excitation of electrons with visible or ultraviolet light to atomic or molecular orbitals. Energy gaps exists and of which values are determined of E=hν where E is energy, h is Planck's constant, and ν frequency equal to c/λ with c in the speed of light and λ a wavelength. Wave-particle duality is shown through h/λ=mc. Hamiltonians, Born-oppenheimer approximation, Jablonski diagrams all help to illustrate electrons in orbit. A spectrometer measures light as it is passed through matter, a transparent medium, and the promotion of an electron in it's ground state to an excited state. It deals with a white light excitation source, sample, and detector.
