Für empfindliche und hochaufgelöste Messungen sind Spektrometer mit starken Magnetfeldern nötig, aus welchen sich Resonanzfrequenzen bis 1,2 GHz ergeben. So wird beispielsweise entschlüsselt, wie Nukleinsäuren und Proteine interagieren und dabei ihre Konformation ändern.","PeriodicalId":49786,"journal":{"name":"Nachrichten aus der Chemie","volume":"51 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140367882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
