<p>Document new Spinach 2.12 spin-boson functionality (PR 195)</p> <p><b>New page</b></p><div>{{DISPLAYTITLE:mev2hz.m}} __NOTOC__<br /> Converts meV energy units used in solid state physics and phonon spectroscopy into Hz units preferred in magnetic resonance. The conversion is nu = E/h with CODATA values of the elementary charge and the Planck constant. Arrays of any dimensions are supported.<br /> <br /> ==Syntax==<br /> <br /> hz=mev2hz(mev)<br /> <br /> ==Parameters==<br /> <br /> mev - an array of values in milli-electronvolts<br /> <br /> ==Outputs==<br /> <br /> hz - an array of values in Hz<br /> <br /> ==Examples==<br /> <br /> A phonon mode reported at 82 meV by an inelastic neutron scattering experiment, declared as a seven-level vibrational mode:<br /> <br /> % Phonon frequency in Hz<br /> frq=mev2hz(82);<br /> <br /> % Phonon mode with seven levels<br /> sys.isotopes={'E','V7'};<br /> inter.modes.frqs={[] frq};<br /> <br /> ==Notes==<br /> <br /> # Derivatives of spin interactions with respect to atomic displacements should be converted into Hz before they are passed to [[cart2mode.m]].<br /> <br /> ==See also==<br /> [[kelvin2hz.m]], [[icm2hz.m]], [[hz2icm.m]], [[cart2mode.m]], [[hartree2joule.m]], [[Kernel utilities]]<br /> <br /> ''Version 2.12, authors: [[Ilya Kuprov]]''</div>
