Chemical exchange rate study by NMR CPMG methodMohorič, Aleš (Avtor) Stepišnik, Janez (Avtor) nuclear magnetic resonanceAnalysis of the NMR CPMG method is presented that enables direct sampling of the spectral-density function of the chemical exchange processes. The approach is demonstrated on a solution of sucrose in water. The result confirms that the method can provide insight into the details of the dynamics of molecular conformations beyond a single-parameter description by an exchange rate. The results of the method are not limited to a single exchange process but can be of advantage if a large and potentially unknown number of exchange processes is contributing to the dynamics of a spin system.20232023-11-29 14:12:21Članek v reviji152584UDK: 537.635ISSN pri članku: 0937-9347DOI: 10.1007/s00723-023-01621-zCOBISS_ID: 167752451sl
