The technique is suitable for both identification of chemical bonds and studying more detailed phenomena like molecular interactions, material strain, crystallinity, defects, and bond formations. Raman scattering has one major weakness however: it is a very low probability process. The weak signals require very sensitive detection systems, which leads to a high probability of picking up signals from origins other than the sample. This complicates the analysis of the results and increases the risk of misinterpreting data. This work provides an overview of the sources of spurious signals occurring in Raman spectra, including photoluminescence, cosmic rays, stray light, artefacts caused by spectrometer components, and signals from other compounds in or surrounding the sample. The origins of these false Raman peaks are explained and means to identify and counteract them are provided.<\/jats:p>","DOI":"10.1002\/anie.202219047","type":"journal-article","created":{"date-parts":[[2023,9,13]],"date-time":"2023-09-13T06:34:48Z","timestamp":1694586888000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Evading the Illusions: Identification of False Peaks in Micro\u2010Raman Spectroscopy and Guidelines for Scientific Best Practice"],"prefix":"10.1002","volume":"62","author":[{"given":"Jakob","family":"Thyr","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering Uppsala university  Box 35 75103 Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2759-7356","authenticated-orcid":false,"given":"Tomas","family":"Edvinsson","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering Uppsala university  Box 35 75103 Uppsala Sweden"},{"name":"Energy Materials Laboratory, Chemistry: School of Natural and Environmental Science Newcastle University  Newcastle Upon Tyne NE1 7RU UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,9,13]]},"reference":[{"key":"e_1_2_10_1_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0CS01059F"},{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.4803740"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s42247-019-00052-6"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/cryst10010038"},{"key":"e_1_2_10_5_1","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1007\/978-3-642-12522-5_6","volume-title":"Confocal Raman Microsc.","author":"Fries M.","year":"2010"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/min11020177"},{"key":"e_1_2_10_7_1","doi-asserted-by":"crossref","unstructured":"A.
