| Abstract: | Abstract Absorption and cmission spectroscopies, which are widely utilized by chemists, can be classified as one–photon spectroscopy. A molecule is excited from its ground state of energy E0 to thc excited state of Ee by the absorption of one photon of frequency given by the Bohr's condition (hω=Ee-E0). The reverse transition is accompanied by the emission of one photon of the same frcquency. Therefore, the molecular state energies can be directly obtained by the photon encrgies absorbed or emitted. Infrared, microwave, electronic absorption, and emission spectroscopies belong to this category of one–photon spectroscopy. |
