Abstract:INTRODUCTIONThere have been a number of publications [1][2][3][4][5] dealing with the temperature variation of nuclear quadrupole resonance frequencies in terms of the well-known Bayer-Kushida expression [6][7][8]. The derivation of the Einstein temperature, 0r, for the torsional modes in the solid state have generally involved two-stage trialand-error calculations. We wish to point out that as the Bayer-Kushida expression may be differentiated with respect to each of the variables, namely v 0 and 0j in the si… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
