What are the main applications of UV spectroscopy?5 answersUV spectroscopy has various applications in different fields. It is used for structural analysis of compounds in Chemistry, Biochemistry, Biology, and Medicines. It is also used to measure the energies of valence states of metallic, semiconducting, and adsorbate-covered surfaces in catalysis, organic electronics, optoelectronic devices, and photovoltaics. UV spectroscopy is a powerful method for studying planetary surface composition and atmospheric composition through reflectance measurements, stellar/solar occultations, and direct imaging of airglow and auroral emissions. It is a versatile and powerful analytical method for investigating catalysts in both liquid-phase and solid-state, under in situ and operando conditions, providing insight into the working principles of heterogeneous catalysts, homogeneous catalysts, electrocatalysts, and photocatalysts. UV spectroscopy can simultaneously measure electronic transitions of organic molecules and transition metal oxides or ions, and it is often combined with other analytical methods to provide complementary information.
How do UV rays affect the environment?5 answersUV rays have various effects on the environment. They can degrade natural organic matter (NOM) in terrestrial and aquatic ecosystems, leading to the emission of carbon dioxide and carbon monoxide, as well as other products that can be easily degraded by microbes. UV light can also impact prebiotic chemistry in liquid water on the surface of a planet with an atmosphere, affecting the synthesis of molecules relevant to abiogenesis. Additionally, UV radiation can modify the terrestrial carbon balance, potentially affecting nutrient cycling and the carbon cycle. In aquatic ecosystems, UV radiation can affect the growth, reproduction, and photosynthetic production of primary producers, such as cyanobacteria, which play a crucial role in carbon dioxide cycling. UV radiation is part of the electromagnetic radiation from the sun and is modified by atmospheric conditions, geographic factors, and human activities, contributing to the cumulative UV dose on the Earth's surface.
