Feb 23, 2010 · A new approach of pulse sequence programming of diffusion sequences called inclusive-DOSY or I-DOSY has recently been published by Gareth Morris and Matthias Nilsson.

Diffusion Ordered SpectroscopY (DOSY) utilizes magnetic field gradients to investigate diffusion processes occurring in solid and liquid samples.

The 2D DOSY contour plots, which are processed differently than curve fitting, tend to have much large room of uncertainty in the diffusion constants shown along the Y axis. Here we give the steps using …

The above command will execute a dosy script that will generate a gradient table consisting of 32 points between 5 to 80 % gradient power linearly. It will then automatically determine the receiver gain …

Diffusion-ordered spectroscopy (DOSY) seeks to separate the NMR signals of different species according to their diffusion coefficient. A series of spin echo spectra is measured with different …

Jun 9, 2025 · DOSY is particularly useful for analyzing complex mixtures and systems, where multiple components are present. By separating the components based on their diffusion coefficients, DOSY …

Figure 3.2: Example of a DOSY spectrum showing the different diffusion behavior of Ethylenglycol and Caffeine dissolved in D2O. Parameters used for acquisition are given in the Appendix.

The current DOSY package includes four basic 2D-DOSY sequences: Dbppste, DgcsteSL, Doneshot, and Dbppsteinept. To set up any of the experiments, start with recording a normal s2pul spectrum on …

DOSY (Diffusion Ordered Spectroscopy) Background In DOSY, the spins are gradient-encoded by their z-position in the NMR tube. After a brief diffusion time (Δ) the spins are decoded.

DOSY experiment can be used to resolve the spectra of mixtures, or it may be used to determine the size of molecules and aggregates. The diffusion experiments can be performed in one dimension as …
