AbstractA new method of quantitative estimation of the exchange constants of magnetisations between different states by means of cross peaks on a T1–T2 topogram obtained from stimulated echo experiments for nuclear quadrupole and nuclear magnetic resonances is proposed.

Abstract A new method for the separation and identification of ambrein in ambergris using adsorption chromatography and 1H and 13C Fourier transform nuclear magnetic resonance spectroscopy (FT-NMR) is presented. We demonstrated the effectiveness of this method by analyzing an approximately 85-year-old sample of suspected ambergris from the New Bedford Whaling Museum (New Bedford, MA). Results prove that ambrein remains a major constituent of ambergris even after 85 years of storage under ordinary conditions.
