Theory of Intrinsically Strain Broadened Line Shapes for Magnetic Resonance Absorption Within a Non-Kramers Doublet.
ARMY MISSILE RESEARCH DEVELOPMENT AND ENGINEERING LAB REDSTONE ARSENAL AL PHY SICAL SCIENCES DIRECTORATE
A theoretical model was calculated for the line shape of magnetic resonance absorption for transitions within a non-Kraers doublet for the point group symmetries C3V and Oh. This was done for both the acoustical paramagnetic resonance and the electron paramagnetic resonance line shapes. The asymmetric broadening of the absorption distribution is interpreted on the basis of the spin-lattice coupling. For the case of C3V symmetry, the calculation was done for both electric radio frequency field and magnetic radio frequency field induced transitions, the necessary condition for the former being a lack of inversion symmetry.
