Nuclear-Spin Conversion Relaxation Processes in Dimethyl- <i>s</i> -Tetrazine-Doped <i>n</i> -Octane Measured by Spectral-Hole-Burning Techniques

Abstract

For the first time, nuclear-spin conversion rates are measured over a dynamic range which covers 7 orders of magnitude. The technique used is spectral hole burning. Between 1.5 and 4 K, Raman-type processes dominate. Above 4 K, the relaxation runs into an activated regime.
