摘要：

The total lineshape (TLS) analysis of a two-site system undergoing chemical exchange is subject to difficulties associated with the temperature dependence of the lineshape parameters. A logarithmic approach is developed in order to deal with this problem and its use is demonstrated by application to the case of N,N-dimethyltrichloroacetamide. The extraction of the temperature dependence of T2 at each site from the TLS results provides information on the molecular reorientation which could otherwise have been overlooked. © 1979.
