text: NMR spectroscopic research includes the following steps:
  *Extraction of carbohydrate material (for natural glycans)
  *Chemical removal of moieties masking regularity (for polymers)
  *Separation and purification of carbohydrate material (for 2D NMR experiments, 10 mg or more is recommended)
  *Sample preparation (usually in DO)
  *Acquisition of 1D spectra 
  *Planning, acquisition and processing of other NMR experiments (usually requires from 5 to 20 hours)
  *Assignment and interpretation of spectra (see exemplary figure)
  *If a structural problem could not be solved: chemical modification/degradation and NMR analysis of products
  *Acquisition of spectra of the native (unmasked) compound and their interpretation based on modified structure
  *Presentation of results
