Determining the molecular structure of organic compounds is very important for understanding the material world at the molecular level and promoting the development of modern organic chemistry. The use of modern instrumental analysis methods can quickly and accurately determine the molecular structure of organic compounds. The most widely used methods for determining molecular structure in organic chemistry are the four major spectroscopic methods: ultraviolet spectroscopy, infrared spectroscopy, nuclear magnetic resonance and mass spectrometry. Ultraviolet and visible spectrum (ultraviolet and visible spectrum) is abbreviated as UV. UV Spectrum Prediction https://www.computabio.com/uv-spectrum-prediction-service.html
