can you give a comprehensive list of rf values.
rf: Radio Frequency?
I am uncertain what the context of rf is.
rf probably is related to chromatography. They are the retention factors for thin layer chromatography; i.e., TLC. I looked on www.google.com an this is what I found.

To obtain a comprehensive list of RF (retention factor) values in the context of thin layer chromatography (TLC), you would typically need to consult specialized books, scientific literature, or databases that provide this information. Here's a step-by-step guide to help you find this information:
1. Begin your search by using online databases such as PubMed, ScienceDirect, or ACS Publications. These databases contain numerous scientific articles where you may find RF values for different compounds.
2. Use relevant keywords to narrow down your search. For example, you could use terms like "thin layer chromatography," "RF values," and the specific compound or class of compounds you are interested in.
3. Browse through the search results and look for articles that discuss RF values in the context of TLC. These articles may present tables or figures containing RF values for various compounds.
4. Access the full text of relevant articles. If you don't have direct access to an article, you can often access it through academic libraries or request it from the authors.
5. Another valuable resource is chromatography reference books or handbooks. These contain compiled information on RF values for a wide range of compounds and can be found in libraries or purchased online.
It is worth noting that RF values can vary depending on the solvent system, TLC plate, and chromatographic conditions used. Therefore, it is important to consider the specific methodology and conditions reported with the RF values found.
