① linear spectrum. Composed of narrow spectral lines. Linear spectrum of light waves are single atomic gas or metal vapor issued, it is known as the linear spectrum atomic spectroscopy. When the atomic energy transition from a lower energy level to a higher energy level butyl acetate, it radiates a single wavelength of light. Strictly speaking, this single wavelength monochromatic light does not exist, due to the energy level itself has a certain width and a Doppler effect and other reasons, there will always atomic spectral lines radiated with a width (see line broadening); i.e., within a narrow range of wavelengths still contain a variety of different wavelength components. Atomic Spectroscopy by wavelength distribution reflects the internal structure of atoms, each atom has its own special spectral series. Through the study of atomic spectra can understand the structure of atoms inside the sec-butyl acetate, quotes, or samples contained components of qualitative and quantitative analysis. Scattering spectroscopy, Raman spectroscopy is the most common spectroscopic techniques. When light passes through substances Shandong sec-butyl acetate, in addition to transmission of light absorption and light, but also observed in scattered light. In addition to including the frequency of the scattered light incident outside the original (Tinder ear scattering and Rayleigh scattering), also includes some new frequency. This scattering is called to generate a new frequency Raman scattering, its spectrum is called the Raman spectrum. Raman scattering intensity is extremely small, approximately one-thousandth of Rayleigh scattering. The nature and intensity of the Raman frequency, polarization and other marks of the scattering material. Such information can be derived from the knowledge structure of matter and material constituents. This is the reason the Raman spectrum has a wide application. Because Raman scattering is very weak, so until 1928 was only discovered Indian physicist Raman, etc.. When they are irradiated with a mercury lamp monochromatic certain liquids, the liquid in the scattered light was observed in the new frequency is lower than the frequency of the incident light spectrum. Raman, who announced their discovery of a few months later, the Soviet physicist Lantz see grid, also independently reported the presence of crystals of this effect.
