✦ Synopsis

Partially resolved hyperfine structure arising from H,Br nuclear-spin-nuclear-spin coupling has been identified in each Brnuclear quadrupole component of the l,,, +O,,,, transition of H,O...HBr. Lineshape simulation leads to a value of D,,= -23 (2) kHz for the spin-spin coupling constant for both H,0...H79Br and H20...H8'Br. An apparent inconsistency between this value and the respective Br-nuclear quadrupole coupling constants x0.=424.326( 9) and 354.490( 2) MHz is resolved by allowing for the influence of the HZ0 electric charge distribution on the value ofkn.

Molecules with multiple bonds are challenging for computations of nuclear spin-spin coupling constants. Tbis can be referred to the asserted importance of non-contact mechanisms, to sharp geometry variations as well as to the handling of the electronic structure problem. We employ a recently develop
