Classical Interpretation of T1rho and T2rho Relaxation

Michael Carl¹, Mark Bydder², Eric Han¹, Graeme Bydder²

We present a simulation model based solely on classical equations to study spin-lattice relaxation in the rotating frame. Without the confound of a quantum mechanical treatment, this model allows for an intuitive understanding of spin locking such as T1rho dispersion, oscillations caused by residual dipolar interactions (RDI), and T2rho.
