摘要
A method for estimating parameters of exponentially damped sinusoidal transients has been applied to a NMR spectrum of ethyl-benzene. As it uses the peak derivatives rather than the classical Fourier ones, it makes them thinner and therefore allows an important resolution improvement . When such separated peaks are pure lorentzian ones, it is possible to estimate their five characteristic parameters, i.e. frequency, amplitude, damping factor, initial phase and time-delay. Gaussian peaks may be treated in the same way.
