“…Acetone. The acetone ratio (f p /f d ) is found to be in fair agreement with the data previously obtained at a lower magnetic field of 1.5 T and 4.7 T with rotation [22,23]. In the present experiment the acetone frequencies are related to the position of the maximum of the lines, while for an interpretation in terms of magnetic moments one has to separate the dominant proton and deuteron modes and weak contributions related to molecules with incomplete substitution of hydrogen for deuterium, (CD) 3 (CHD 2 )CO, which affect the maximum of stronger lines.…”

Magnetic moments of free and bound deuteron and triton are considered and new results for their magnetic moments (in units of that of the proton) and their g factors are presented. We report on a measurement with medium-pressure hydrogen deuteride (HD) at 10 atm, which is to be compared with the previous measurement done at 100 atm. We confirm that the high pressure used in former experiments caused no systematic effects at a level of 10 ppb. We also reexamined a theoretical uncertainty related to screening effects in HD and HT molecules and found that previously it was underestimated. The medium-pressure result obtained for the free deuteron µ d /µ p = 0.307 012 206 5(28) with a fractional uncertainty of 9.1·10 −9 is free of systematic effects related to former high-pressure experiments. The reevaluated result for triton is µ t /µ p = 1.066 639 908(10) with a fractional uncertainty of 9.3 · 10 −9 .

“…In earlier studies, hydrogen was usually used as a solvent gas; however, even neglecting this difference, one can obtain similar results. It was found that J eff (D, H) determined from a 1 H NMR spectrum of an HD/He mixture at 130 bar is 43.138(10) Hz which agrees with the value reported by Neronov et al [11], 43.115 (12) Hz. The latter measurement was performed at room temperature at the same pressure for a mixture of D 2 and HD generated in situ from the reaction between LiH/LiD and D 2 O.…”

“…Next, Beckett [10] reported 43.130 (15) Hz for this value. Subsequently, a similar value, 43.115 (12) Hz, was reported by Neronov et al [11]. Recently, Helgaker et al [12] determined that J(D, H) = 43.26 (6) Hz.…”

“…Likewise, the influence on J eff (D, H) of the dissolution of HD in liquids is notable. For example, according to Neronov et al [11] the separation between the peaks for hydrogen deuteride dissolved in liquid CCl 4 is reduced to 42.64 Hz. Thus, the purpose of this work is to provide a value for the spin-spin coupling of hydrogen deuteride that is unperturbed be external interactions or by the effects of nuclear relaxation.…”

“…The values of spin–spin coupling obtained from liquid-state NMR are perturbed by solvent–solute interactions. For example, dissolution of HD in carbon tetrachloride decreases the multiplet splitting by 0.5 Hz . Therefore, in order to reduce the influence of intermolecular interactions, one can take advantage of gas-phase NMR experiment.…”

Indirect Spin–Spin Coupling Constants in the Hydrogen Isotopologues

The results of experimental and theoretical studies of indirect spin-spin coupling constants for hydrogen deuteride (HD), hydrogen tritide (HT), and deuterium tritide (DT) are described. The reduced coupling constants obtained from the gas-phase NMR (nuclear magnetic resonance) experiment conducted at 300 K are 2.338(1), 2.334(3), and 2.316(1) × 10(20) T(2) J(-1), while the ab initio values computed at the full configuration interaction level of theory equal 2.349(3), 2.343(3), and 2.322(3) × 10(20) T(2) J(-1) for HD, HT, and DT, respectively. The agreement of the experimental and theoretical results is improved when proper treatment of the influence of nuclear relaxation on the NMR spectrum is applied. However, there is a minor discrepancy between experiment and theory, exceeding the estimated error bars; potential sources of this discrepancy are discussed.
