| Abstract: | Measurements of chlorine T₂ in liquid HCl and DCl have been made over the temperature range of -40°C to 60°C. Estimates of the reorientational correlation time made possible by the chlorine measurements were used to evaluate the proton intra-molecular dipole contribution which was subtracted from the total intra-molecular contribution to obtain the proton spin-rotational contribution. The magnitude of the spin-rotational contribution thus obtained compares with that estimated by Krynicki and Powles.⁸ Deuteron T₁ times in liquid DCl were measured over the temperature range of -75°C to 25°C and found to differ considerably both in magnitude and temperature dependence from deuteron T₂ times. Estimates of the quadrupole contribution to the deuteron (1/T₁) and, thus, a value of 2.0 x 10¹⁷ volts/cm² for the electric field gradient at the deuteron site in DCl were made by use of the reorientational correlation time from chlorine measurements. The difference between experimental deuteron (1/T₁) and the deuteron quadrupole contribution to (1/T₁) was considered to be due to a deuteron-chlorine scalar interaction. The scalar contribution to the deuteron (1/T₁) and the experimental deuteron (1/T₂) were used to estimate the scalar coupling constant and deuteron exchange time in DCl. |
