Precision of volume integrals in two-dimensional NMR

The precision of measurements of peak volumes in a correlation map obtained from a two-dimensional NMR experiment is investigated. It is shown that the noise correlation function in the frequency domain and the volume standard deviation both reduce to a product of one-dimensional factors. The ratio...

Summary:The precision of measurements of peak volumes in a correlation map obtained from a two-dimensional NMR experiment is investigated. It is shown that the noise correlation function in the frequency domain and the volume standard deviation both reduce to a product of one-dimensional factors. The ratio of a peak volume to its standard deviation is derived and is related to the usual signal-to-noise ratio. The effects of sine-bell windowing and exponential multiplication are found to be slight.
