Bromine (Br) is a deep red, volatile liquid at room temperature and is part of the halogen group in the periodic table. It is highly reactive and has a variety of applications. Bromine is widely used as a flame retardant in textiles, plastics, and electronic devices, helping to reduce flammability. It is also employed as a disinfectant for swimming pools and spas, where it effectively kills bacteria, viruses, and other pathogens. Additionally, bromine compounds are used in the production of pharmaceuticals, agricultural chemicals, and photographic films. Surface analysis of bromine is important because it helps understand its reactivity and interactions with other materials. Techniques like XPS provide detailed information about the elemental composition and chemical states of bromine on surfaces, which is crucial for optimizing its use in various applications.
X-ray exposure has been found to degrade brominated organics, and so it is advised to record a pre- and post- analysis scan of the Br 3d region to check for sample damage of a new material.[2]
See our page on sample damage for more advice on dealing with sample damage.
Br 3d can be readily fir with a Shirley background and Voigt-type LA lineshapes.
