The evolution of nuclear spin magnetization during a radiofrequency pulse in the absence of relaxation or coupling interactions can be described by three Euler angles. The Euler angles. in turn. can be obtained from the solution of a Riccati differential equation; however. https://znbqho1adl5s.celticwiki.com/1456164/application_of_qvp_method_to_winter_precipitation_observation_based_on_polarimetric_radar
