| Abstract: | In
order to get the simplified spectra for separation of carbonyl groups, the
spectral editing of NMR signals has become a useful technique for complex
molecules. E-HMQC is a 1H-dedected, edited-pulse angle and
two-dimensional NMR experiment which allows the selective detection of CH, CH2
and CH3 signals. The product operator theory is widely used for
analytical description of the spectral editing NMR experiments for weakly
coupled spin systems. In the present study, analytical descriptions of the 2D 2H-dedected
E-HMQC NMR experiment have been presented for weakly coupled ISn (I=½; S=1; n=1, 2, 3) spin systems by using the
product operator theory. By using obtained FID values, theoretical discussion
and experimental suggestions for sub-spectral editing of CD, CD2 and
CD3 groups have been made. |
