Long nuclear spin coherence times for molecules trapped in high-purity solid parahydrogen
Abstract
We measure the ensemble transverse relaxation time ( T 2 * ) and spin-echo coherence time ( T 2 ) of the proton spin of HD molecules trapped in solid parahydrogen. By using high-purity parahydrogen matrices, we are able to measure significantly longer T 2 and T 2 * times than seen in prior work. We also measure the longitudinal spin relaxation time T 1 . We examine how these parameters scale with the matrix purity and find limits on the coherence time from the parahydrogen matrix itself.
