| contents | Solid-state NMR provides a wide variety of experimental techniques to detect and analyze a material's chemical and physical environment. Here, we offer a theoretical demonstration of a new approach that could be a promising candidate for characterizing the local environments and shifts. Prethermalization by applying a spin-locking pulse brings a new research paradigm in solid-state NMR and has not been hitherto explored for such purposes. We show that a prethermal state can also be effective in this case. A prethermal state is described using its lifetime and the value of transverse magnetization. Using these two variables, we successfully detect the changes in the environmental parameter and chemical and dynamical shifts (such as Lamb shifts). Our results exhibit that the lifetime increases with increasing environmental correlation time. On the other hand, the transverse magnetization decreases with the increase in the strength of the shift parameter. Based on these observations, we propose that the prethermalization dynamics can yield important information on local environment. |
