Mirror symmetric broadband homodecoupled perfect echo

Pulse sequences in Bruker format for achieving broadband homodecoupling in w1 is described. The technique is implemented in a conventional 2D TOCSY experiment.A real and constant time mode version of the mirror symmetric decoupling approach is provided.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Measurement of long range H,C couplings in natural products in orienting media: a tool for structure elucidation of natural products

In this paper we show that water insoluble compounds dissolved in poly-γ-benzyl-glutamate are amenable to the measurement of a number of homo- and heteronuclear dipolar couplings. The sensitivity and experimental precision of dipolar couplings are sufficient to obtain a good match with the structure. In order to achieve the necessary precision for H,C dipolar couplings between protons and carbons that are not directly bound a new method for the measurement of heteronuclear long range couplings is introduced that allows a one-parameter fit to a HSQC-based experiment as reference experiment. The methodology is applied to menthol (1R, 3S, 4R)
