Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Research Support, U.S. Gov’t, Non-P.H.S., Journal of Magnetic Resonance called Conditional rotations of heteronuclear coupled spins, Author is O’Donnell, Lauren F.; Ridge, Clark D.; Walls, Jamie D., which mentions a compound: 600-05-5, SMILESS is O=C(O)C(Br)CBr, Molecular C3H4Br2O2, Related Products of 600-05-5.
The authors present a new pulse sequence that conditionally excites I spin magnetization only in the presence of a nonzero heteronuclear coupling to an S spin. The pulse sequence, referred to as the reverse INEPT pathway selective pulse or RIPSP, generates a pure I spin rotation by an angle that depends upon the heteronuclear coupling constant in InS spin systems. Exptl. demonstrations are shown in 13C labeled chloroform, dichloromethane, and toluene samples and in unlabeled 2,3-dibromopropionic acid and brucine samples.
