To confirm the assignment, 2-D homonuclear double quantum filtered correlated spectroscopy (DQF-COSY) was recorded.
There is also a restriction on the permissible quantum numbers due to the homonuclear nature of the dimer since the basis states must be antisymmetric with respect to exchange of the two nuclei.
HOMONUCLEAR DECOUPLING AND 2-D NMR IN UNDERGRADUATE RESEARCH AND TEACHING.
It begins with an introduction to the techniques themselves, it defines the underlying concepts and, once the appropriate terminology has been presented, it sequentially introduces a whole variety of pulse sequences in an orderly fashion from the homonuclear decoupling processes to the heteronuclear ones (short- and long-range decouplings are discussed).
Chapter 2, by far the largest part of the book because of the many implications of the chemical bond, introduces a model of bonding in homonuclear and heteronuclear diatomics, multiple and delocalized bonds in hydrocarbons, and the stereochemistry of chemical bonds in polyatomic molecules, in a word, a model of the strong first-order interactions originating the chemical bond.
Hxcoqf and inv41plrndqf heteronucleair pulse programs were used respectively for CHCorr and HMBC experiments; 2D homonuclear correlation pulse programs, Cosyqf45 and Cosyqfrl were used for COSY experiments.

It is based on the application of multiple pulse homonuclear decoupling.
