| Zusammenfassung: | Copyright © 2015 John Wiley & Sons, Ltd. The density matrix of a spin S=9/2 excited by a radiofrequency pulse is calculated. The interaction involved during the excitation of the spin system is first-order quadrupolar. Consequently, the results are valid for any ratio of the quadrupolar coupling ωQ to the pulse amplitude ω1 . The behavior of the central transition intensities versus the pulse length is discussed. The (115) In and (113) In nuclei in a powdered sample of indium phosphide (InP) are used to illustrate the results. It is found that the ratio of the quadrupolar coupling constants determined in this work is in excellent agreement with the ratio of the quadrupole moments of the two nuclei |
