Does anyone have the spectra for sulfur? In class we did this using a flame test, where we put the sulfur in a flame over a bunsen burner and used a spectra scope to find sulfur's spectra, but I seem to have lost this data. I've been looking on the web, but I don't know which ones are accurate.
To find the spectrum of sulfur accurately, it is recommended to consult reliable sources such as scientific journals, databases, or reputable educational websites. Here is a step-by-step guide on how to access the spectrum of sulfur:
1. Start by searching for "sulfur spectrum" or "sulfur atomic emission spectrum" on a search engine like Google.
2. Look for results from reputable scientific sources or educational institutions. Examples of reliable sources include scientific journals like the Journal of Chemical Physics or websites such as the National Institute of Standards and Technology (NIST).
3. Access the website or article that contains the sulfur spectrum. Make sure it provides detailed information about the methodology used to obtain the spectrum.
4. Locate the spectrum image or data. This may be in the form of a graph, a table of wavelengths and corresponding intensities, or a digital spectrum image.
5. If the source provides the actual numeric values of the spectrum, you can note down the wavelengths at which sulfur emits light. Typically, sulfur will emit light at wavelengths around 400-560 nm.
6. Use the information you found to reconstruct the emission spectrum of sulfur or compare it to the data you obtained from the flame test in class.
Remember, it is important to rely on trustworthy sources to ensure the accuracy of the spectral data you find.
To find the spectral data for sulfur, there are a few reliable sources you can consult.
1. NIST Atomic Spectra Database (ASD): The National Institute of Standards and Technology (NIST) provides a comprehensive database of atomic spectra, known as the ASD. You can access it online at https://physics.nist.gov/asd/. Once on the website, search for "sulfur" or its atomic symbol "S" to find the available spectral data.
2. Scientific Journals: Sulfur's spectra may have been published in scientific journals. Access reputable scientific journals through your school's library or online databases. Use keywords like "sulfur spectra" or "sulfur emission spectrum" to narrow down your search and locate relevant articles.
3. Spectral Databases: There are various online spectral databases such as the American Astronomical Society's database (https://www.aas.org/grants-and-prizes/aas-fellows/aas-astronomical-database-service-ads) or the European Space Agency's Herschel Science Archive (https://www.cosmos.esa.int/web/herschel/data-products). These databases collect and provide access to a wealth of spectral data, including sulfur.
Remember to critically evaluate the sources you find to ensure the accuracy and reliability of the data. Additionally, note that the flame test you mentioned might not be the best method to obtain an accurate and comprehensive spectrum for sulfur. Instead, spectroscopic techniques like emission or absorption spectroscopy are commonly used to generate more precise and detailed spectra.
