| 英文摘要 | Methods for measuring longitudinal relaxation times of protons in heavily overlapped H-1 NMR spectra are introduced and exemplified using a solution of cholesteryl acetate. The methods are based on 1-dimensional and 2-dimensional maximum quantum NMR spectroscopy (MAXY), which makes possible the selective detection of CH, CH2 and CH3 H-1 NMR resonances. A modification of the BIRD pulse sequence to achieve selective inversion of protons bonded to either C-12 or C-13 is given. The approach should rnd application in studies of molecular dynamics where isotopic enrichment is not possible and the level of available sample dictates the use of H-1 NMR spectroscopy. |
