Glycan Optimized Dual Empirical Spectrum Simulation (GODESS) is a web service, which has been recently shown to be one of the most accurate tools for simulation of ¹H and ¹³C 1D NMR spectra of natural carbohydrates and their derivatives. The new version of GODESS supports visualization of the simulated ¹H and ¹³C chemical shifts in the form of most 2D spin correlation spectra commonly used in carbohydrate research, such as 1H–1H TOCSY, COSY/COSY-DQF/COSY-RCT, and ¹H–¹³C edHSQC, HSQC–COSY, HSQC–TOCSY, and HMBC. Peaks in the simulated 2D spectra are color-coded and labeled according to the signal assignment and can be exported in JCAMP-DX format. Peak widths are estimated empirically from the structural features. GODESS is available free of charge via the Internet at the platform of the Carbohydrate Structure Database project (http://csdb.glycoscience.ru).
