The double-transition NQR spectra of deuterium in catechol-(O)- d 2 , two phases of resorcinol-(O)- d 2 , and one phase of hydroquinone-(O)- d 2 have been examined at 77 K to obtain site and line pairing assignments for these materials. The interpret

Deuterium and nitrogen quadrupole coupling data on phenylphosphonic acid (PPA) and two ternary cocrystals of PPA with catechol and pyridine are reported. These data are discussed in terms of the crystal structures and the hydrogen bonding present. De

As part of a program for the examination of hydrogen-bonded materials by deuterium NQR, we have attempted a detailed assignment of the normal and DTQR spectrum of hydroquinone-(O)-d 2 . The crystal structure of this material at ambient temperature co

The pure quadrupole spectra of dipolar coupled nuclei in solids contain weak combination and difference bands, usually referred to as DTQR transitions, together with the normal (e.g. allowed) lines. The forbidden lines contain useful information abou

Nuclear quadrupole resonance spectra of deuterium are reported for anhydrous 2-imidazolidone (ethylene urea), its hemihydrate, phthalimide, and benzamide at 77 K. Imidazolidone-(N,N′)-d2 shows a single deuteron site per asymmetric unit, with e2qQ/h

A 35Cl2H double-resonance study of deuterium in the orthorhombic solid phase of deuterium chloride has been made at temperatures below the transition to the cubic phase (105.03 K). The temperature dependence of the deuterium coupling constant was
