Detailed Description
The technical scheme of the present invention is further described in non-limiting detail below with reference to the preferred embodiments and the accompanying drawings.

The principle of the raman spectrometer 8 is that when a single monochromatic light beam with a frequency v0 is applied to a sample, the molecules scatter the incident light. Most light simply changes the direction of propagation of the light, and therefore scatters, while the frequency of the transmitted light passing through the molecule remains the same as the frequency of the incident light, and this scattering is called Rayleigh scattering; there is also scattered light, which is about 10-6-10 of the total scattered light intensity, which not only changes in the direction of propagation but also changes in the frequency of the scattered light, and thus differs from the frequency of the excitation light, and is therefore called raman scattering, in which the scattered light frequency is reduced relative to the frequency of the incident light, and is called stokes scattering, and thus in the opposite case, the frequency-increased scattering, called anti-stokes scattering, is usually much stronger than anti-stokes scattering, the raman spectrometer 8 usually measures mostly stokes scattering, also commonly referred to as raman scattering, the frequency difference v between the scattered light and the incident light being called raman shift, which is independent of the frequency of the incident light, and is only related to the structure of the scattered molecule itself, raman scattering being due to a change in the molecular polarization rate, the raman shift being dependent on a change in the vibrational energy level of the molecule, and Δe reflecting a change in the energy level of a different chemical bond or group-characteristic molecule, and thus also a raman shift corresponding to the characteristic.
