Background
Along with the continuous progress of cultivation technology, the growing period of fruits is shorter and shorter, and along with the aggravation of environmental pollution, the diseases and insect pests of fruits are heavier and heavier, and most of fruits can be ripened and marketed after being continuously put into medicine for many times. Many pesticides are toxic and after use, the crop carries pesticide residues, which cause the crop to contain toxins. The purpose of using pesticides is to kill pests, but the pesticides can cause adverse effects on human health, and the raman spectrum is a scattering spectrum. The raman spectroscopy is an analysis method for analyzing a scattering spectrum different from the frequency of incident light based on the raman scattering effect found by the indian scientist c.v. raman to obtain information on the vibration and rotation of molecules, and is applied to the study of molecular structures. Light is irradiated onto the substance to cause elastic scattering and inelastic scattering. Elastically scattered light is the same component as the excitation light wavelength, and inelastically scattered light has longer and shorter components than the excitation light wavelength, collectively referred to as the raman effect. The raman effect is the result of the interaction of photons with optical phonons. Typically, the stokes line is stronger than the anti-stokes line. This is due to the Boltzmann distribution, the number of particles in the vibrational ground state is much larger than in the vibrational excited state. Advantages of raman spectroscopy: raman spectroscopy provides a rapid, simple, reproducible and more important non-invasive qualitative and quantitative analysis that does not require sample preparation, and the sample can be measured directly by a fiber optic probe or by glass, quartz, and fiber optics.
